Register

Wraps Stytch's register_start and register WebAuthn endpoints, the Credential Manager API on Android and the CredentialProvider API on iOS. Call this method to prompt the user to enroll a new WebAuthn factor and save the factor in Stytch.

Call webauthn.register inside an event callback triggered by a user gesture.

You can listen for successful user updates anywhere in the codebase with the stytch.user.onChange() method or useStytchUser() hook if you are using React.

Note: If a user has enrolled another MFA method, this method will require MFA. See the Multi-factor authentication section for more details.
