Proton Pass Extension Keeps Logging Out or Shows Locked
Workaround available Chrome, Firefox, Edge, Brave Updated October 21, 2026
Quick answer
Reload or update the extension, then sign out and back in. Clearing browser site data signs the extension out. If you're locked out entirely, a signed-in reset from a device that's still logged in lets you change your password.
Most likely fix: Reload and update the extension.
Symptoms
The extension stays locked after entering the PIN, signs itself out, refuses to sign back in, or you're signed out of the app and extension after an update.
Why it happens
- Browser site data was cleared
- Outdated or partly updated extension
- Session problem after an app update
How to fix it
Try these in order — the most common fix is first.
1. Reload and update the extension
- Open your browser's extensions page
- Disable and re-enable Proton Pass, or click Reload
- Update it to the latest version
2. Sign out and back in
- Open the extension menu and sign out
- Sign in again with your Proton account and set your PIN
3. Don't clear Proton's site data
- If you clear cookies on exit, add proton.me as an exception so the extension isn't signed out
4. Use a signed-in reset if you're locked out
- Keep Proton Pass logged in on at least one mobile device
- Request a signed-in reset from that device to change your password
5. Send logs to support
- Open Settings > General > Application logs
- Attach the logs to a support ticket
