Proton Pass Autofill Not Working on Android
Ongoing Android (Brave, Vanadium, GrapheneOS) Updated October 21, 2026
Quick answer
Set Proton Pass as the preferred Passwords, passkeys & accounts service, then toggle it off and on. In Brave and GrapheneOS Vanadium the popup often doesn't appear at all; switching the autofill provider back and forth or restarting the browser is the only workaround users report.
Most likely fix: Set Proton Pass as the autofill service.
Symptoms
No Proton Pass popup or keyboard suggestion bar on login fields, autofill works in some browsers but not Brave or Vanadium, or app logins don't appear in the keyboard.
Why it happens
- Proton Pass is not the selected autofill service
- Browser compatibility problems in Brave and Vanadium
- Battery optimization stopping the Proton Pass service
- Native app logins not matched to the saved website item
How to fix it
Try these in order — the most common fix is first.
1. Set Proton Pass as the autofill service
- Open Android Settings > Passwords, passkeys & accounts
- Set Proton Pass as the preferred service
- If it's already selected, switch it off and on again
2. Vanadium: toggle the browser autofill setting
- In Vanadium settings, set autofill to use another service
- If it stops working, switch it to Google and back to 'Autofill using other service'
- Restart Vanadium if the popup still doesn't appear
3. Allow Proton Pass to run in the background
- Open Settings > Apps > Proton Pass > Battery
- Set it to Unrestricted
4. Try a different browser
- Brave users report Bitwarden works but Proton Pass doesn't; until it's fixed, use another Chromium browser or Firefox for logins
- Report the issue from the app's feedback option
