ASU uses two-factor authentication to protect you and your personal data and as an additional measure to protect against cyber security threats. Two-factor authentication uses a combination of your password, something you know, and a device that you own, like a phone, to access ASU systems. When you need to access important data at ASU, you will be asked to verify who you are by sending a signal to a device you own. We suggest you select two or more devices. This will keep you productive if any one device is unavailable.
