Android 16. Bitwarden 202.10.0. Vivaldi 7.6.3810.117. Phone: Pixel 10 pro fold.
When trying to autofill username/password, Bitwarden opens and I select the entry but it doesn’t fill any of the fields. I need to open Botwarden manually, copy/paste username and password manually. Autofill works fine with Chrome and Brave, just not with Vivaldi.
Browser extensions are not officially supported in Android. This is why some features don’t work.
@the1avi Welcome to the forum!
I just tested it on this Community Forum with Vivaldi (Android 15) and could autofill without any problem. – Does it work for you on the forum website?
If not, I probably would recommend to visit this site: [Short Guide / Tips] Autofill on Android
And I must say, with passkey and Vivaldi (on Android) I’m also unlucky at the moment.
Ah… I just saw what @grb wrote. And good point! If you’re trying to use the browser extension “on mobile”, you should change to the mobile app instead. (and please clarify)
I am not using a browser extension. I am using the Android app.
Anyway, I just tried it again with the community forum and it did populate the username/password correctly. I then tried the same with some other sites where the information was not populating and it did it now correctly. I verified that the credentials are not stored with Vivaldi and since the Bitwarden app was last updated Oct 3, 2025 and Vivadli was last updated Oct 16, 2025 I have no idea why it started working suddenly now without any updates to Android, Vivaldi, nor Bitwarden, It didn’t work when I posed my question few hours ago. I am dumbfounded.
Ok, then I’ll change the tag from app:browser(-extension) to app:mobile.
Hm. For now, I think I’ll mark your post as “solution” then.
If autofill works in general and you “only” have specific sites/apps where it doesn’t work, you can always report those here:
