Method Details

getUsername

public Optional<String> getUsername()

The username of the user to authenticate, if the user has already been identified.

Mutually exclusive with getUserHandle().

If this or getUserHandle() is present, then RelyingParty.startAssertion(StartAssertionOptions) will set PublicKeyCredentialRequestOptions.getAllowCredentials() to the list of that user's credentials.

If this and getUserHandle() are both absent, that implies a first-factor authentication operation - meaning identification of the user is deferred until after receiving the response from the client.

The default is empty (absent).

See Also:

• Client-side-discoverable credential

getUserHandle

public Optional<ByteArray> getUserHandle()

The user handle of the user to authenticate, if the user has already been identified.

Mutually exclusive with getUsername().

If this or getUsername() is present, then RelyingParty.startAssertion(StartAssertionOptions) will set PublicKeyCredentialRequestOptions.getAllowCredentials() to the list of that user's credentials.

If this and getUsername() are both absent, that implies a first-factor authentication operation - meaning identification of the user is deferred until after receiving the response from the client.

The default is empty (absent).

See Also:

• getUsername()
• User Handle
• Client-side-discoverable credential

getUserVerification

public Optional<UserVerificationRequirement> getUserVerification()

The value for PublicKeyCredentialRequestOptions.getUserVerification() for this authentication operation.

If set to UserVerificationRequirement.REQUIRED, then RelyingParty.finishAssertion(FinishAssertionOptions) will enforce that user verificationwas performed in this authentication ceremony.

The default is UserVerificationRequirement.PREFERRED.

getTimeout

public Optional<Long> getTimeout()

The value for PublicKeyCredentialRequestOptions.getTimeout() for this authentication operation.

This library does not take the timeout into account in any way, other than passing it through to the PublicKeyCredentialRequestOptions so it can be used as an argument to navigator.credentials.get() on the client side.

The default is empty.

builder

public static StartAssertionOptions.StartAssertionOptionsBuilder builder()

toBuilder

public StartAssertionOptions.StartAssertionOptionsBuilder toBuilder()

getExtensions

@NonNull
public @NonNull AssertionExtensionInputs getExtensions()

Extension inputs for this authentication operation.

If RelyingParty.getAppId() is set, RelyingParty.startAssertion(StartAssertionOptions) will overwrite any appId extension input set herein.

The default specifies no extension inputs.
