If you see an “Invalid Token” error when opening the Bluesky mobile app, you cannot view your feed, post updates, or send messages. This error occurs because the app’s authentication token, which proves you are logged in, has expired or become corrupted. The Bluesky app stores this token locally and refreshes it automatically, but network issues, app updates, or account changes can break the refresh process. This article explains the root cause of the invalid token error and provides clear steps to fix it on both iOS and Android devices.
Key Takeaways: Fixing the Bluesky Invalid Token Error
- Settings > Account > Sign Out: Clears the corrupted token and lets you start a fresh login.
- Settings > App Storage > Clear Cache: Removes temporary data that may hold an outdated token.
- Reinstall the Bluesky App: Wipes all local data including the token and forces a clean authentication.
Why the Bluesky Mobile App Shows Invalid Token
The Bluesky app uses an OAuth-based token system to keep you logged in. When you sign in the first time, the app receives a short-lived access token and a longer-lived refresh token. The access token expires after a set period, usually a few hours. The app then uses the refresh token to get a new access token without asking you for your password again.
The invalid token error appears when this refresh process fails. Common triggers include:
- App update: The update may change how tokens are stored, invalidating the old token.
- Account password change: Changing your Bluesky password on another device or the web invalidates all existing tokens.
- Network interruptions: A poor connection during token refresh can leave the token in a half-updated state.
- Clock drift: If your phone’s system clock is incorrect, the token’s timestamp fails validation.
The app cannot recover from a corrupted token on its own. You must manually clear the token by signing out or clearing app data.
Steps to Resolve the Invalid Token Error
Follow these steps in order. Stop once the error disappears.
Step 1: Sign Out and Sign In Again
- Open the Bluesky app
If the error blocks the main screen, tap the profile icon in the bottom toolbar to reach your account page. - Go to Settings
Tap the gear icon in the top-right corner of the profile page. - Scroll to Account
In the Settings menu, find the Account section near the bottom. - Tap Sign Out
Confirm the sign-out action when prompted. The app returns to the login screen. - Sign In Again
Enter your Bluesky handle or email and password. Tap Sign In. If a two-factor code is required, enter it.
This clears the old token and issues a fresh one. If the error persists, continue to Step 2.
Step 2: Clear the App Cache
- Open your phone’s Settings
On iOS, go to Settings > General > iPhone Storage. On Android, go to Settings > Apps. - Find Bluesky in the app list
Tap the Bluesky app entry. - Clear the cache
On iOS, tap Offload App. This removes the app but keeps documents and data — then reinstall from the App Store. On Android, tap Storage > Clear Cache. Do not tap Clear Data yet. - Reopen Bluesky
Launch the app and sign in again.
Clearing the cache removes temporary files that may hold a stale token. If the error remains, proceed to Step 3.
Step 3: Reinstall the Bluesky App
- Delete the Bluesky app
On iOS, press and hold the app icon and tap Remove App > Delete App. On Android, press and hold the app icon and tap Uninstall. - Restart your phone
Power off and turn on your device. This clears any residual system-level token data. - Reinstall Bluesky from the app store
Download the latest version from the App Store or Google Play Store. - Sign in with your credentials
Open the app and log in. The error should be gone.
Reinstalling removes all local data, including the corrupted token and any cached settings.
If Bluesky Still Shows Invalid Token After Reinstalling
If the error persists after a clean reinstall, the problem may be on the server side or with your account.
Check Bluesky Server Status
Visit the Bluesky Status page at status.bsky.app. If the API or authentication service shows an outage, wait until the service is restored. The token error will resolve automatically once the servers are back online.
Reset Your Password
If your token was revoked due to a security event, resetting your password forces all tokens to be invalidated. Go to the Bluesky website, log in, and change your password under Settings > Account > Change Password. Then sign in again on the mobile app with the new password.
Check Your Phone’s Date and Time
Go to Settings > General > Date & Time on iOS or Settings > System > Date & Time on Android. Enable Set Automatically. If it is already enabled, disable it and re-enable it to force a sync. An incorrect clock causes token validation to fail.
Bluesky Invalid Token Error vs Other Login Errors
| Item | Invalid Token | Incorrect Password |
|---|---|---|
| Error message | “Invalid token” or “Token expired” | “Incorrect username or password” |
| Root cause | Stored authentication token is corrupt or expired | Provided password does not match the account |
| Fix | Sign out, clear cache, or reinstall the app | Reset password via the Bluesky website |
| Affects | Only the mobile app | All devices and the website |
The invalid token error is always a client-side issue. The incorrect password error requires server-side verification. If you can log in on the Bluesky website but not the app, the token is the problem. If you cannot log in anywhere, the password is the problem.
Conclusion
You can now resolve the Bluesky invalid token error on your mobile app by signing out, clearing the cache, or reinstalling the app. If the error returns frequently, check your phone’s date and time settings and ensure automatic time sync is enabled. As a proactive step, enable two-factor authentication in the app under Settings > Account > Two-Factor Auth to reduce the chance of token revocation from unauthorized access attempts.
