[FEATURE] OTP verification for email and password authentication.

## What feature would you like to see?

One Time Password when using email and password sign up method to verify users mail..
## How would you use it?

I know there is already a feature for Email link authentication, but that doesn't allow password management. Also implementing OTP based authentication is very easy for app side developer. So this would be far easy to use than the current email link authentication with password management.
