We’ve been providing email-based two-factor authentication (2FA) for a looong time. And recently we’ve received some feedback about the placing of a direct-login link within the email that is sent out.

How Shield’s Two-Factor Authentication Portal Works

With the portal you’re prompted to enter any or all of your 2FA codes to confirm your login. If you have turned on email-based 2FA and “Enable Auto-Login Links” option, then you’ll get an email with both the code you need, and also a link.

There are 2 points to note:

  1. the two-factor portal has a 5 minute window. If you miss it, you have to start your login from scratch.
  2. the auto-login link can only ever be used once

If email is your 2nd factor and you click a link received in 2FA verification email, it’ll log you straight into the site automatically.

Auto-Login Links is a convenient feature that simplifies the login process for the all users who have Two-Factor Authentication (2FA) by email enabled for their user login.
