All Mobile SDK methods for email OTP require you to initiate an action first. Check out our guide on email OTP authentication for more details.

​
Enroll email

Start enrollment for a new email OTP authenticator by sending the user an email containing an OTP code. This method is typically used when you’ve not yet verified the user’s email address. 
await authsignal.email.enroll(email: "jane.smith@authsignal.com")
If you’ve already verified a user’s email address independently of Authsignal, you can alternatively use a Server SDK to enroll the user programmatically.
