Signing in with a passkey

Refer to How do I get started with Microsoft MFA? for instructions on registering passkeys. Depending on how your passkey is stored, you may have slightly different experiences signing in.

  • In some cases, you may not even need to type in your UIC email address and will instead be prompted to use a saved passkey on the initial login screen. When this happens, you can simply select the passkey and you will be immediately logged in!

  • If you do enter your UIC email address and select Next, you will then be prompted to choose one of your available passkeys.
    • An example is shown for Bitwarden and also Apple Passwords on a computer. Select the passkey and you will be immediately logged in!

    • On a mobile device, the interface will be somewhat different, but the options are generally the same, depending on what passkeys you have available. This example shows a mobile device with passkeys stored in Microsoft Authenticator, Bitwarden, and Apple Passwords. Any of the available options can be used. Simply select the passkey you want to use and you will be immediately logged in!

Signing in with a cross-device passkey

Sometimes, you may need to log in to your university account on a device that doesn't have a passkey already saved on it. So long as you have a UIC passkey available on your mobile device (e.g. in your Google Password Manager or in Apple Passwords) you can still log in using that passkey.

Note: this process requires that both the device you are logging in on, and your mobile device, have an Internet connection and have Bluetooth enabled.

  1. In this case, when prompted select Use a phone, tablet or security key.
