Windows 11: Logging-in to BW webvault with a passkey, stored in Bitwarden vault, prompts for master password

[Neuron5569]

Hello and welcome back

To log into Bitwarden with a passkey without a password successfully:

• The passkey authenticator (security key, password manager) must support PRF extensions.
• The browser must support the PRF extension (Chrome, Edge, and Firefox do).

Bitwarden currently doesn’t support the PRF extension as a passkey authenticator, so you can’t use it to log in without a password.

Support for Storing PRF-Capable Passkeys in Bitwarden Vault

Talking about the implementation of Passkeys where the Bitwarden Extension/App acts as the A in CTAP. (Authenticator) PRF support → For one of my accounts, I have Bitwarden master password in Bitwarden. I was planning on adding my Bitwarden as a “Login with Passkeys” for Bitwarden, but noticed Bitwarden didn’t support encryption for login with passkeys. I would love to see support.

PS:

• Storing a passkey for logging into your Bitwarden account in Bitwarden could create a circular dependency. It should probably be used for convenience only, even if PRF support is added in the future.
• Passkey authenticators that support the PRF extension currently include FIDO2 security keys and Google Password Manager.
