(Future) passkey support on Iode OS

Passkeys can now be used with the first services. They already work on Android with a Google account and Chrome.
Iode OS runs without Play services. Currently, Passkeys cannot be used under Iode OS.

Is there any information whether MicroG will implement Passkey in any form?

In addition, external password managers are supposed to be supported starting with Android 14. Can we already estimate whether this will also work without Play services?
Thank you!
