Part 1 of 5 in a stack: #231 (this), #232, #233, #234, #235
This stack adds support for persistent pinUvAuthTokens (the CTAP 2.2+
pcmrpermission). A persistent token lets a credential manager list the passkeys on a security key without re-prompting for the PIN on every app launch or replug. It is read-only credential management only and cannot assert, create, update, or delete. Storage is supplied by the caller, and tokens are invalidated on PIN change or authenticator reset.This PR
Groundwork, with no behaviour change:
pcmrpermission value and the getInfo capability check used to detect persistent-token support.
