I'm asking for FIDO U2F, not an authenticator app and no Fingerprint.
FIDO U2F is a second hardware device like e.g. a Yubikey and we use this for every access e.g. for cloud software (SaaS) and services like Google Drive, or e.g. Facebook as well.
The link you posted show a feature request from May 2019
is this on the roadmap already?
