I might be hijacking this thread here, but is there a reason the Android app doesn’t support the “Connect to additional browsers” feature that I see on my mac? Or any other way to allow us to use custom browsers.

Hi Dave, one more thing that might help. Titanium (io.github.jqssun.helium) is already on Google's privileged apps list for passkeys, including its release signing certificate: https://www.gstatic.com/gpm-passkeys-privileged-apps/apps.json

So Google has already vetted it. Right now creating a passkey from Titanium works in 1Password, but signing in with it doesn't, which looks like 1Password just isn't picking up that entry.

I confirmed this by setting Google Password Manager as my passkey provider. Registering and signing in with a Google-stored passkey works end-to-end in Titanium, while the 1Password-stored one still fails at sign-in.

Happy to test if useful.
