Tramp has support for 2FA security. Please add the fingerprint prompt to
the user option tramp-security-key-confirm-regexp. If there is a second
message, telling you that the security key (your finger :-) has been
confirmed, add this message to the user option
tramp-security-key-confirmed-regexp.

If it doesn't work, send me Tramp traces (tramp-verbose 6 shall be sufficient).

> Thanks,

Best regards, Michael.
