What is Email Two-Factor Authentication?

WS Email Two-Factor Authentication adds a layer of security by adding a second step to the login process. It takes something you know (i.e. your password) and adds a second factor, typically something you have (such as your email). Since both are required to log in, the threat of a leaked password is lessened.

One of the most common and simplest forms of Two-Factor Authentication is Email Addresses. With Email 2FA, in addition to your regular username & password, you also have to enter a 6-digit code that regenerates every 30 seconds. Only your token device (typically an email address) will know your secret key and be able to generate valid one-time passwords for your account. We recommend enabling Email 2FA.

This system also gives you the ability to provide your customers and admins with Email Two-Factor Authentication, which will send a code to your clients/admins' email upon login, before proceeding to the client area/admin area, you would need to enter the provided code.
