AnkiDroid Login: Sign In, Sync & Fix Errors (2026 Guide)

AnkiDroid login trips up a surprising number of users — not because the process is complex, but because AnkiDroid, Anki desktop, and AnkiWeb are three separate pieces of software from two different teams, and understanding how they relate to each other is the prerequisite for everything else. This guide walks through account creation, signing in on Android, setting up bi-directional sync, and fixing the most common login and sync errors. At the end, we cover export paths so your data is never stranded — whether you stay with Anki or move on.

If you are brand-new to Anki and have not yet installed it on your desktop, start with our Anki download guide for Mac before setting up AnkiDroid — the desktop app is where most users do their initial deck building. And if you need a refresher on what a deck actually is, see our what is an Anki deck explainer first.

What Is AnkiDroid & AnkiWeb?

Three names, three things. They are easy to confuse if nobody explains them upfront.

Anki is the original desktop application, created by Damien Elmes. It runs on Windows, macOS, and Linux. It is free, open-source, and the primary authoring environment where most users create and edit decks.

AnkiWeb is Anki's free cloud sync service at ankiweb.net. It serves two purposes: storing an encrypted copy of your decks for cross-device access, and hosting a browser-based review interface. An AnkiWeb account is the bridge between Anki desktop and AnkiDroid — the same anki sign in works on every device. Without it, syncing between devices is not possible.

AnkiDroid is a separate open-source Android app maintained by a volunteer community independently of Damien Elmes. It is not an official Anki product, but it is fully compatible with AnkiWeb and uses the same deck format (.apkg). As of AnkiDroid v2.17, it ships with FSRS support and has largely closed the feature gap with the desktop client. It is free on the Google Play Store, with no in-app purchases.

The important implication: AnkiDroid login is not a login to a separate account. You use the same AnkiWeb credentials you created on ankiweb.net. No separate AnkiDroid account exists. If you are trying to create one, stop — you are in the wrong place.

There is also a frequently misunderstood app called Anki Pro, which is a completely different product with no connection to Anki desktop or AnkiDroid. Our Anki Pro vs Anki comparison explains the difference in detail. The short version: they do not share accounts, data, or any technical infrastructure.

Creating Your AnkiWeb Account

How do I create an AnkiWeb account?

AnkiWeb account creation takes under two minutes. Here is the exact sequence:

1. Open a browser and go to ankiweb.net.
2. Click Sign Up in the top-right corner.
3. Enter your email address and choose a password. Passwords are case-sensitive. Avoid leading or trailing spaces — this is one of the most common causes of "invalid credentials" errors later.
4. Click Sign Up. You will receive a confirmation email.
5. Open the email and click the verification link. Until you verify, sync will be blocked with a "confirm email" error.
6. Log in to ankiweb.net to confirm the account is active.

That is it. You do not need to upload any decks through the web interface. Decks reach AnkiWeb through the Anki desktop sync or AnkiDroid sync — not through manual upload, though manual .apkg upload is available as a fallback.

Password advice: Use a password manager. AnkiWeb passwords are case-sensitive and the field does not trim whitespace, so a trailing space typed on a touchscreen becomes part of the stored password. If you ever get "invalid credentials" despite being certain your password is correct, a hidden space character is the most likely culprit.

Logging Into AnkiDroid on Android

Once your AnkiWeb account exists, the anki flashcards login on Android is straightforward. The steps below apply to AnkiDroid v2.16 and later; the UI in older versions differs slightly but the path is the same.

1. Install AnkiDroid from the Google Play Store. Search for "AnkiDroid Flashcards" — the developer is "AnkiDroid Open Source Team." Verify this before installing, as there are lookalike apps in the store.
2. Open AnkiDroid. On first launch you will see an empty deck list.
3. Tap the three-line menu (hamburger) in the top-left corner.
4. Tap Settings.
5. Tap AnkiDroid then AnkiWeb account. In some builds the path is Settings → Sync → AnkiWeb account.
6. Enter the email and password from your AnkiWeb account. Type carefully — do not copy-paste from a source that may include surrounding whitespace.
7. Tap OK. AnkiDroid will attempt to validate the credentials against ankiweb.net.
8. On success, return to the deck list and tap the sync icon (two circular arrows) in the top bar. Your first sync will pull all decks from AnkiWeb to the device.

If your AnkiWeb account already has decks from Anki desktop sync, they will appear after the first AnkiDroid sync completes. If it is a new account with no data, the deck list remains empty until you add cards either in AnkiDroid or on desktop and sync again.

For iPad users, the process is different — AnkiDroid is Android-only. See our Anki on iPad setup guide for the iOS workflow, which uses the paid AnkiMobile app rather than AnkiDroid.

Syncing Decks: Desktop to Mobile

Bi-directional sync between Anki desktop and AnkiDroid works through AnkiWeb as an intermediary. Neither app syncs directly to the other — both push to and pull from AnkiWeb, which acts as the single source of truth.

The recommended sync workflow:

1. Always sync before studying. When you open AnkiDroid, tap the sync icon before starting a review session. This pulls any changes made on desktop.
2. Always sync after studying. When you finish reviewing on AnkiDroid, sync again. This pushes your review results to AnkiWeb so they are available on desktop.
3. Apply the same discipline on desktop. Open Anki desktop, sync, study, sync. If you review on both devices without syncing in between, you will create a conflict.

To set up sync on Anki desktop (if you have not already): open Anki, go to Tools → Preferences → Syncing, enter your AnkiWeb credentials, and click Sync Now from the main toolbar. The desktop client and AnkiDroid use the same AnkiWeb account, so there is nothing platform-specific to configure once credentials are entered on each device.

Sync does not happen automatically in the background on AnkiDroid by default. Some users enable Auto sync on app open/close in Settings → Sync to reduce the chance of forgetting. This is especially useful if you review on mobile during a commute and return to desktop later in the day.

Understanding spaced repetition scheduling is useful here — when Anki syncs review results, it merges the scheduling data for each card. Our spaced repetition techniques guide explains the FSRS algorithm that AnkiDroid v2.17+ uses by default and how review timing decisions are made.

Troubleshooting Login Errors

Why can't I log in to AnkiDroid with valid credentials?

The most common AnkiDroid login failures and their causes:

Invalid Credentials

This error means AnkiWeb rejected the email/password combination. Before assuming you have forgotten your password, check these first:

• Trailing space in password. On Android keyboards, autocorrect sometimes appends a space after the last character. Clear the password field, disable autocorrect temporarily, and retype manually.
• Wrong email address. If you have multiple email accounts, confirm which one you registered with at ankiweb.net.
• Caps Lock / case sensitivity. AnkiWeb passwords are case-sensitive. Passwords entered via touchscreen keyboards with auto-capitalize enabled may have an unintended capital first letter.
• Account email not verified. Log in to ankiweb.net on desktop. If you see a "please verify your email" banner, click the resend link and complete verification before retrying AnkiDroid login.

If none of the above applies, use the Forgot Password link at ankiweb.net to reset. AnkiDroid will accept the new credentials immediately after reset.

What if AnkiDroid shows "network error" on login?

A network error during login or sync means AnkiDroid could not reach ankiweb.net. This is almost always a connectivity issue, not an account issue.

• VPN interference. Corporate or privacy VPNs sometimes block connections to ankiweb.net. Disable the VPN and retry.
• Captive portal. If you are on a hotel, airport, or campus Wi-Fi that requires browser login, AnkiDroid cannot authenticate. Open a browser first, complete the portal login, then retry.
• Restrictive firewall. Some corporate or school networks block non-standard ports. Switch to mobile data to confirm this is the issue.
• DNS resolution failure. Try switching to a public DNS (8.8.8.8 or 1.1.1.1) in your Android network settings.

SSL / Certificate Errors

SSL errors during AnkiDroid login ("certificate verification failed" or similar) usually have one of two causes:

• System clock is wrong. TLS certificate validation compares the current time against the certificate's validity window. An Android device with a clock more than a few minutes off will fail SSL handshakes. Go to Settings → Date & Time and enable "Set time automatically."
• Intercepting proxy. Corporate networks that perform SSL inspection inject their own root certificate. AnkiDroid does not trust custom enterprise CAs by default. Use mobile data, or ask your IT department to add ankiweb.net to the inspection bypass list.

Login Succeeds But Sync Fails

If you can log in but sync throws an error, the most common causes are a full AnkiWeb storage quota (100MB limit on the free tier), an incompatible deck format from a third-party add-on, or a sync conflict that needs manual resolution. The next section covers conflict resolution.

Resolving Sync Conflicts

A sync conflict occurs when Anki detects that changes were made on two devices since the last successful sync. It happens when you studied on desktop and on AnkiDroid without syncing between sessions. AnkiDroid v2.16+ handles most conflicts automatically using a merge algorithm, but when the merge fails or Anki is uncertain, it presents a dialog.

The dialog asks you to choose between two options:

• Upload to AnkiWeb — the current device's state overwrites AnkiWeb. Any changes made on the other device since the last sync are lost.
• Download from AnkiWeb — AnkiWeb's state overwrites the current device. Any local changes since the last sync are lost.

How to choose: identify which device has the more recent or more valuable changes. If you spent the last hour adding cards on desktop and have not synced yet, run the desktop sync first (choosing "Upload" if prompted). Then open AnkiDroid and sync there (choosing "Download" if prompted). This sequence pushes desktop changes to AnkiWeb, then pulls them to AnkiDroid.

If you studied on AnkiDroid and forgot to sync before studying on desktop, you are in the harder situation. Review history from one device will be lost no matter which direction you choose. The only prevention is consistent sync discipline: sync in, study, sync out, every session, every device.

One important nuance: Anki's merge algorithm handles review history surprisingly well. If both devices recorded reviews for different cards, the merge usually succeeds automatically. The conflict dialog only appears when the same card was reviewed on both devices, or when structural changes (deck deletions, card template edits) conflict.

Exporting Decks — Your Exit Strategy

Can I export my AnkiDroid decks to another flashcard app?

Yes. Anki's .apkg format is the most portable deck format in the flashcard ecosystem. Here is how to export from AnkiDroid:

1. In AnkiDroid, long-press the deck you want to export.
2. Tap Export from the context menu.
3. Choose .apkg format. This exports cards, scheduling data, and media.
4. Share or save the file to your preferred location (Google Drive, local storage, email to yourself).

The .apkg file can be imported directly into Anki desktop on any platform. This is also useful as a backup strategy independent of AnkiWeb.

For migration to other tools: the Anki desktop client (not AnkiDroid directly) can save decks as plain text with tab-separated fields, which most other flashcard platforms accept as import. The workflow is: generate an .apkg on AnkiDroid → open it in the Anki desktop client → save the deck as tab-separated text from desktop → import into the destination app.

If you are building decks from PDFs or web content, our PDF to Anki AI guide covers several tools that generate .apkg files directly from documents, which simplifies the import workflow considerably. For a broader look at spaced repetition tools, our best flashcard app guide compares seven platforms across algorithm quality, price, and platform coverage.

Anki Alternatives Worth Knowing

AnkiDroid is excellent, but it is not the right tool for every situation. Here is an honest assessment of the main alternatives, including where each genuinely wins.

Feature	AnkiDroid	Quizlet	Flashcard Maker
Platform	Android	Web, iOS, Android	Chrome (desktop)
Price (free tier)	Free, no ads	Limited free; Plus $2.99/mo billed annually ($35.99/yr) or $7.99/mo month-to-month	Free
Spaced repetition	FSRS v5 (Again/Hard/Good/Easy)	Basic Learn mode, no FSRS	FSRS (Again/Hard/Good/Easy)
Card creation	In-app editor; import .apkg	In-app editor; AI assist (paid)	Right-click context menu on any webpage
Import formats	.apkg, .colpkg, text	Word, Google Docs, image	Quizlet TSV, CSV
Export formats	.apkg, .colpkg	Quizlet TSV (limited)	Quizlet TSV
Sync / backup	AnkiWeb (100 MB free)	Cloud sync across devices	None (local-first via IndexedDB)
Offline use	Yes	Paid tier only	Yes
Account required	No (AnkiWeb optional for sync)	Yes	No

Quizlet

Quizlet is the most-used flashcard platform in the world, primarily because of its accessible design and enormous library of pre-made study sets. It runs on web, iOS, and Android. The free tier has been progressively restricted since 2022 — offline access and advanced learning modes now require Quizlet Plus at $35.99/year (or $7.99/month billed monthly).

Where Quizlet wins: existing shared sets for specific courses, classroom environments where the teacher distributes sets, and users who want a polished mobile interface without configuration overhead. Where it loses to AnkiDroid: algorithm quality (Anki's FSRS is more sophisticated than Quizlet's Learn mode), pricing at scale, and data portability. See our full Anki vs Quizlet comparison for a detailed head-to-head on algorithm, pricing, and specific use cases.

Flashcard Maker (Chrome Extension)

Flashcard Maker is a desktop Chrome extension — not a mobile app — so it is not a replacement for AnkiDroid on Android. What it is: the fastest way to create flashcards from web content on a laptop or desktop computer.

The workflow: highlight text on any webpage, right-click, select "Create Flashcard." The card is saved locally in IndexedDB with no account required. Built-in FSRS spaced repetition handles scheduling. You can study in the Chrome side panel without leaving your current tab.

Where it fits in an Anki workflow: Flashcard Maker works well as a deck-building companion for people who do research or reading on their laptop. Capture cards while reading documentation or articles, organize them into decks, then export as a Quizlet-ready TSV file or import from Quizlet TSV and CSV. There is no Anki .apkg export, and no mobile app. If your primary study device is an Android phone, AnkiDroid is the right tool there. If you also read on a laptop, Flashcard Maker covers that surface efficiently.

For users looking at alternatives to Quizlet more broadly, Flashcard Maker is worth considering alongside Anki depending on where you spend most of your study time.

Brainscape

Brainscape uses a confidence-based repetition system (rate 1–5 after each card) rather than Anki's Again/Hard/Good/Easy buttons. The algorithm is solid. Its key advantage is professionally curated content for GRE, LSAT, CPA, CFA, and language certification exams. If you are studying for one of those and want quality pre-made decks rather than building your own, Brainscape is worth the subscription cost. Pro pricing: $19.99/month, $9.99/month on a 6-month billing cycle ($59.94), or $7.99/month billed annually ($95.88).

RemNote

RemNote treats notes and flashcards as the same document. You write notes using a double-colon syntax (Term :: Definition) and RemNote auto-generates cards. This is genuinely useful for users who take detailed notes anyway and do not want to maintain a separate card system. The spaced repetition is competent. The interface is complex. Best for knowledge workers, not casual students.

When to Stay with AnkiDroid

AnkiDroid is the right choice if you need free, full-featured FSRS spaced repetition on Android, compatibility with the enormous AnkiWeb shared deck library, and a tool that works offline without any subscription. For most serious learners on Android, nothing else in this price range (“free”) comes close.

For study technique guidance that works regardless of which tool you choose, our flashcard study techniques guide covers five evidence-based approaches including how to structure cards for maximum retention.

If you are deciding between Anki's ecosystem and something else, the honest summary: Anki wins on algorithm, portability, and price. It loses on setup friction and mobile polish. Every alternative on this list trades some combination of algorithm quality or data freedom for a smoother onboarding experience. Whether that trade is worth it depends entirely on how long you intend to study and how much configuration you are willing to accept upfront.

Frequently Asked Questions

How do I create an AnkiWeb account?

Go to ankiweb.net in a browser, click Sign Up in the top-right corner, enter your email and a case-sensitive password, then submit. AnkiWeb emails a verification link — click it before attempting an anki sign in from any device, or sync will be blocked with a "confirm email" error. Once verified, the same credentials work as your AnkiDroid login and your Anki desktop sync login. There is no separate AnkiDroid account.

Why can't I log in to AnkiDroid with valid credentials?

The most common cause is a trailing space appended by the Android keyboard's autocorrect, followed by an unintended capital letter from auto-capitalize (AnkiWeb passwords are case-sensitive). Other causes: the AnkiWeb account email was never verified, the wrong email address was used at sign-up, or the account password was recently reset on desktop. Clear the field, disable autocorrect, retype manually, and if all else fails use Forgot Password on ankiweb.net to restore your anki flashcards login.

How do I sync AnkiDroid with Anki Desktop?

Both apps sync through AnkiWeb — never directly to each other. Enter the same AnkiWeb credentials on desktop (Tools → Preferences → Syncing) and on AnkiDroid (Settings → AnkiWeb account). Tap the sync icon in AnkiDroid before and after each study session; do the same on desktop with Sync Now. AnkiWeb acts as the single source of truth, merging review history from both devices when the sync order is respected.

What if AnkiDroid shows "network error" on login?

A network error means AnkiDroid could not reach ankiweb.net. Check four things in order: disable any active VPN (corporate and privacy VPNs frequently block AnkiWeb), complete a captive-portal login in a browser if you are on hotel or campus Wi-Fi, switch to mobile data to rule out a restrictive firewall, and try public DNS (8.8.8.8 or 1.1.1.1) if resolution fails. SSL errors usually mean the device clock is wrong — enable "Set time automatically." See the AnkiDroid Manual for version-specific troubleshooting details.

Can I export my AnkiDroid decks to another flashcard app?

Yes. Long-press a deck in AnkiDroid, tap Export, and choose the .apkg format — this preserves cards, scheduling data, and media. The .apkg file imports directly into Anki desktop on any platform. To migrate to a non-Anki app, open the .apkg on desktop and re-export as tab-separated text, which most flashcard platforms accept. Keep a periodic .apkg export as a backup independent of AnkiWeb.
