^{Originally posted by forrest96 June 2, 2024} Could you add support for FIDO-backed public key authentication in the OpenSSH Server (sshd)? This includes the following algorithms:

• [email protected]
• [email protected]
• [email protected]
• [email protected]

The implementation should be straightforward.

Please add the following configurations to sshd_config to indicate the supported implementations:

• PubkeyAuthOptions

• PubkeyAcceptedAlgorithms
