Your smartphone is a convenient option to verify your identity for two-factor authentication (2FA). If you upgrade to a new phone but are using the same phone number, you can follow instructions to re-activate 2FA on your new device.
Also, it’s a good time to manage the other devices you may have registered by logging in to 2FA.uchicago.edu. You can also print a list of one-time passcodes to use when you don’t have access to your registered devices.
