I need to implement the following. Basically a SignIn with multiple verified email addresses.
1. A first time email/password SignUp. 2. Registered emails - send verification to the email account and verified from the user after click. (this is done). 3. Each of the registered emails plus the initial SignUp email to be a valid email address for email/password SignIn. The password - the same as the initial Sign Up. e.g. the user SignUp with ema...@...com/password, then he registers/verifies two more emails: ema...@...com, email3...com. when he logs in next time he can login with: ema...@...com/password ema...@...com/password ema...@...com/password Security is OK because he is the owner of ema...@...com, ema...@...com and proves it by SignIn to these email accounts. ema...@...com is pending until he does the same as for other email addresses. How to accomplish this?
