# Multi-Factor Authentication
Multi-Factor Authentication (MFA) is the process of using two or more independent factors to verify a user's identity for a login and to access secure data - similar to what you may use with online banking. It protects the user from an unknown person trying to access their data such as personal ID details or financial assets.
• The first factor is something known only to you - your CU username and password.
• The second factor is a single-use code sent to your personal device (mobile phone or tablet) OR a message sent asking for confirmation that you are attempting to log in.
Multi-Factor Authenticate will need to be set up on both your computer and phone and will require re-authentication at least once every 14 days. This is to ensure the security of the device and your personal data.
Multi-Factor Authenticate is used for a wider variety of services including Emails, Microsoft Teams, Digital Services Portal, Student Portal, and many others.
