Passkey Flex Android SDK core functions

PassageFlex.Passkey.authenticate()

Parameters

Returns

String

Authenticate the user. Returns a nonce.

There are two ways to authenticate users with passkeys. Review the Authenticate Implementation Guide to learn more.

With an external identifier

Authenticate the user using a transaction ID retrieved from the Passage API using a Passkey Flex backend SDK. This requires the user to enter a external identifier (email or username) to authenticate.

Example

val nonce = PassageFlex.Passkey.authenticate(transactionId, activity)

Without an external identifier

Authenticate the user using discoverable credentials. The user is not required to type in any identifier. A typical UX for this flow is "one-click" authentication using a button. The user will be provided all passkey options for the app on the device.

Example

val nonce = PassageFlex.Passkey.authenticate(null, activity)

PassageFlex.Passkey.register()

Parameters

Returns

String

Register the user using the transaction ID you retrieve from the Passkey Flex API using a Passkey Flex backend SDK. You can use the nonce in a backend SDK to verify that Passkey has registered the user successfully.

Example

val nonce = PassageFlex.Passkey.register(transactionId, activity)
