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.

Method parameters

domain* string
is_passkey boolean
session_duration_minutes int
import React, { useCallback } from 'react';
import { Text, TouchableOpacity, View } from 'react-native';
import { useStytch } from '@stytch/react-native';

  const stytch = useStytch();

  const trigger = useCallback(() => {
    stytch.webauthn.register({
      domain: 'example.com',
      is_passkey: true,
      session_duration_minutes: 60,
    });
