Multi-Factor Authentication (MFA) Registration


Multi-factor Authentication (MFA) is a way of verifying that people logging into our systems are indeed the people we think they are.  In these times when malicious and phishing email attacks are a daily occurrence, MFA provides a way to limit the impact of these attacks and help ensure that only authorized people are accessing our systems. This helps us to protect not only our email, but all of our data and applications connected to Office 365.  Simply put, MFA is a method of authentication that requires more than one verification method.  This adds a critical second layer of security when users sign-in to their CAU Office 365 account.  It does this by requiring more than one method of verifying that it is really you logging into the account.
