Mobile passkey (android) - Passkey not supported for this app

Using BW on my Pixel 10 I am getting more and more prompts in mobile apps to define a PassKey (which is nice). If I confirm I get a Bitwarden unlock request (as expected) but then an error “Passkey not supported for this app”. Most recent exemples would be WhatsApp and Revolut.

What gives ?

The “Revolut” app is an open issue (and seems to be an issue on their side, if you read the comments):

 

… and “WhatsApp” worked recently, but just a few minutes ago the corresponding bug report was reopened:

 

So, in general passkeys should work with the Android app. If they don’t work at all, you should look into your configuration (a good way to test it, if you just started using passkeys on Android: it works without issue for me with my forum account here, so try that first). If it’s “only” certain apps: it may be a bug – or an issue “on the other side” (bad implementation), and in both cases, report those as “passkey issues” here: https://github.com/bitwarden/android/issues
