Flutter: Sign in a user through OTP

• Requires either an email or phone number.
• This method is used for passwordless sign-ins where a OTP is sent to the user's email or phone number.
• If you're using an email, you can configure whether you want the user to receive a magiclink or a OTP.
• If you're using phone, you can configure whether you want the user to receive a OTP.
• The magic link's destination URL is determined by the SITE_URL. You can modify the SITE_URL or add additional redirect urls in your project.

Examples

Sign in with email.

await supabase.auth.signInWithOtp(
  email: 'example@email.com',
  emailRedirectTo: kIsWeb ? null : 'io.supabase.flutter://signin-callback/',
);

Sign in with SMS OTP.

await supabase.auth.signInWithOtp(
  phone: '+13334445555',
);

Sign in with WhatsApp OTP

await supabase.auth.signInWithOtp(
  phone: '+13334445555',

);
