User Interaction - Objective-C

The object in charge of selecting an account. This protocol must be conformed by the user of the SDK only when username-less out-of-band authentication is required with multiple accounts.

The service returning the information required to choose the account to be used: it returns all the available accounts and authenticators and also informs whether a given authenticator is compliant with the policy required by the FIDO UAF server for the ongoing operation.

The object handling the outcome of an interaction where the user chooses the account to be used.

The object in charge of selecting the authenticator to be used to perform an operation.

The service returning the information required to choose the authenticator to be used: it returns all the available authenticators, the operation being executed and also informs whether a given authenticator is compliant with the policy required by the FIDO UAF server for the ongoing operation.

The object handling the outcome of an interaction where the user chooses the authenticator to be used.

The object handling the old and new PIN provided by the end-user.

The object providing some contextual information during PIN change.

The object handling the old and new PIN provided by the end-user.

The object in charge of PIN enrollment.

The object providing some contextual information during PIN enrollment.

The object handling the PIN to be enrolled.

The protocol that other user verification context objects conform to.

The object in charge of interacting with the user to do PIN authentication.

The object providing information about the PIN user verification (i.e. the user credential validation) operation to be done.

This object contains the information required to ask the user to authenticate: the authenticator to be used, whether there were previous errors authenticating, etc.

The object handling the outcome of an interaction where the user provides PIN credentials.

This is used with the NMAAuthenticator/pinAuthenticatorAaid.

The object describing the PIN authenticator protection status. It provides information regarding how many retries are available for the end user before locking the authenticator.

The protocol defining the NMAPinPolicy.

The object defining the minimum and maximum length of the PIN.

The object in charge of interacting with the user to do biometric authentication.

The object providing information about the Biometric user verification (i.e. the user credential validation) operation to be done.

The object handling the outcome of an interaction where the user provides biometric credentials.

This is used with the NMAAuthenticator/fingerprintAuthenticatorAaid, or NMAAuthenticator/faceRecognitionAuthenticatorAaid. The particularity of this authenticator with the other authenticators, is that the SDK relies on the operating system prompt to authentication. (i.e. there is no need to develop a GUI to do the authentication when this authenticator is used).

The object in charge of interacting with the user to do authenticate using the device passcode.

The object providing information about the device passcode user verification (i.e. the user credential validation) operation to be done.

The object handling the outcome of an interaction where the user provides device passcode credentials.

This is used with the NMAAuthenticator/DevicePasscodes. The particularity of this authenticator with the other authenticators, is that the SDK relies on the operating system prompt to authentication. (i.e. there is no need to develop a GUI to do the authentication when this authenticator is used).

The protocol that operation or user interaction handlers are derived from.
