Remember how 1Password used to install itself as a custom keyboard that could "type" your passwords into arbitrary text fields anywhere in the OS, before password management specific hooks were added?
It would be nifty if your phone could just connect to other devices as a BT keyboard and type in passwords there too. Probably not worth the actual fuss of pairing a BT device, but if that part were not so painful it could be quite a nice solution.
One major flaw in this approach is the one-way channel (keyboard input) prevents the password manager from knowing if it is supplying credentials to the correct recipient. Phishing attacks are relatively common and users expect a password manager to know these things, even in situations like you have described where it’s clearly impossible. I think this is why this approach hasn’t succeeded in the marketplace and FIDO2/WebAuthn support seem to be table stakes.
Yeah, certainly a proper security module / passkey-type approach is ideal, it would be hard to justify all the bother of developing a bluetooth typer if really the only use-case for it is legacy devices that are old enough to not have an OS supporting the client app, but new enough to still pair with a device pretending to be a bluetooth keyboard.
