Webmail 9.0: Two-Factor Authentication (2FA)

The use of two-factor authentication to prove a user's identity is based on the premise that an unauthorized actor is unlikely to be able to supply both factors required to access an account which utilizes 2FA. If, in an authentication attempt, at least one of the components is missing or incorrect, the user’s identity is not established with sufficient certainty and access to the user's Redtail Webmail account being protected by two-factor authentication remains blocked. 

In Webmail, administrators have the option to enable or enforce Two-factor authentication.

When the Two-factor connection is only enabled, not enforced, you have the option to set it up under Settings → Accounts at your convenience. In such a case, you can log in with just your username and password.

If the administrator of your account has enforced the two-factor authentication for your account, you can read below how to go about setting up 2FA for your account.


2FA Enforced

If the administrator has enforced two-factor authentication, you are required to set it up immediately after you log in for the first time. You cannot use the application until you set up 2FA on your account. To do so:

  1. Launch Webmail.

  2. Login using an authorized username and password. Since your administrator has enforced two-factor authentication, you'll then immediately reach a page to set up 2FA.

  3. Click Begin setup.

  4. Next, you will be prompted to download and install an authentication app on your mobile device. A few options we suggest are listed below: 

    Google Authenticator (iOS) (Android)

    Duo Mobile (iOS) (Android)

    1Password (iOS) (Android)

    LastPass (iOS) (Android)

    Authy (iOS) (Android

  5. Once installed, configure it on your smartphone.

  6. Click Next on the Webmail screen to begin the process of adding this account to the authentication app.

  7. On the authenticator app, enter the code generated on the Webmail screen.

  8. Click Next.

  9. Enter the code generated by your authenticator app and click Verify to complete the two-factor authentication setup.
