@newworldman said in Passkeys not working in latest Opera?:
Android 15 Security Patch Level 1 June 2025 - updated 25 June
Opera - Chromium 137, Security Updates 2025-07-02
Samsung Galaxy S24
I had no problems until a few days ago but in a couple of different applications I’m getting “authentication failed” error in one application (GitHub - but username and password with 2FA is fine) and “the interaction with your security device was cancelled or timed out” in another.
But using the passkeys via Vivaldi is fine.
It sounds like the issue is specific to Opera after the recent updates. Since passkeys still work fine in Vivaldi, the problem is likely a browser-side bug with Opera + Android 15 security patch. Clearing Opera’s privacy/security settings or re-registering the passkey might fix it, otherwise waiting for the next Opera update is probably the safest move.
