tfa_email_support

TFA Email is a lightweight plugin that extends the core functionality of the TFA (Two-Factor Authentication) module by adding support for email-based one-time passcodes (OTP) as a second factor.

By default, the TFA module does not include email as a 2FA option. This plugin fills that gap, allowing you to use email as the second step in the login process, without needing SMS, authenticator apps, or third-party integrations.

Features

1. Seamless integration with the TFA module
2. Sends a one-time passcode (OTP) to the user’s registered email
3. Minimal configuration required
4. Ideal for sites where email is the most accessible 2FA method

Requirements

1. Drupal core
2. TFA module
