Members
dwVersion
The version of this structure.
dwTimeoutMilliseconds
Time that the operation is expected to complete within. This is used as guidance and can be overridden by the platform.
CredentialList
The list of allowed credentials to be used in the assertion.
Extensions
A CBOR map from extension identifiers to their authenticator extension inputs, created by the client based on the extensions requested by the Relying Party. These are optional extensions to parse when performing the operation.
dwAuthenticatorAttachment
The attachment for the assertion. Optional platform vs cross-platform authenticators.
dwUserVerificationRequirement
The effective user verification requirement.
dwFlags
The flags for the assertion.
pwszU2fAppId
Optional identifier for the U2F AppId. Converted to UTF8 before being hashed. Not lower-cased.
pbU2fAppId
If this is non-NULL, then, set to TRUE if the pwszU2fAppid was used instead of PCWSTR pwszRpId.
pCancellationId
Optional cancellation Id. See WebAuthNGetCancellationId for more information.
pAllowCredentialList
An optional list of public key credential descriptors describing credentials acceptable to the Relying Party (possibly filtered by the client), if any. If present, CredentialList will be ignored.
dwCredLargeBlobOperation
The large blob operation.
cbCredLargeBlob
Size of pbCredLargeBlob.
pbCredLargeBlob
A pointer to the large credential blob.
pHmacSecretSaltValues
PRF values which will be converted into HMAC-SECRET values according to the WebAuthN Spec.
bBrowserInPrivateMode
Indicates whether the client is using in-private mode in the browser. An optional parameter that defaults to FALSE.
pLinkedDevice
bAutoFill
cbJsonExt
pbJsonExt
