Struct webauthn_rs::proto::Credential

pub struct Credential {
    pub cred_id: CredentialID,
    pub cred: COSEKey,
    pub counter: u32,
    pub verified: bool,
    pub registration_policy: UserVerificationPolicy,
}

A user’s authenticator credential. It contains an id, the public key and a counter of how many times the authenticator has been used.

Fields

cred_id: CredentialID

The ID of this credential.

cred: COSEKey

The public key of this credential

counter: u32

The counter for this credential

verified: bool

During registration, if this credential was verified then this is true. If not it is false. This is based on the policy at the time of registration of the credential.

This is a deviation from the Webauthn specification, because it clarifies the user experience of the credentials to UV being a per-credential attribute, rather than a per-authentication ceremony attribute. For example it can be surprising to register a credential as un-verified but then to use verification with it in the future.

registration_policy: UserVerificationPolicy

During registration, the policy that was requested from this credential. This is used to understand if the how the verified component interacts with the device, IE an always verified authenticator vs one that can dynamically request it.
