What Is 2 Step Authentication?

2 step authentication can be used to help protect your organization from unauthorized access by requiring two methods (authentication factors) to verify users' identity when logging into Proofpoint Essentials. 2 step authentication helps protect against phishing, social engineering and password brute-force attacks and secures your logins from attackers exploiting weak or stolen credentials.

What Happens When You Turn On 2 Step Authentication?

Authentication Method: SMS

Once 2 step authentication has been enabled for your organization, whenever a user attempts to login, they will be prompted to enter both their password and a passcode sent to their mobile number.

When a user has successfully logged in, they will not be prompted to enter another passcode for 12 hours, however, if a user clears their browser cookies, they will be prompted to enter a new passcode upon their next login.

 

Important: To ensure users can receive a passcode via the SMS authentication method, all in scope users must have a valid mobile number assigned to their account. In the absence of a valid mobile number, users will be unable to login if two step authentication is enabled.
