How to Update Your Security Key

The next time you log in and choose to use your Security Key you may receive a prompt titled "Let's Update Your Security Key"

  1. To update click Continue.
  2. This will open a new window where you will be prompted to interact with your Security Key.
  3. For college provided YubiKeys, make sure it is plugged into a USB port you can reach and tap the blinking key symbol.

If you previously chose "Skip this update" on the prompt, it will ask you again the next time you log in with a Security Key. Also, even if you skip the update you will still be able to continue to use your Security Key as expected in the Chrome web browser.
