Microsoft's short video, Passkeys explained in under four minutes, explains what passkeys are and how they help protect your account. (Watch the video on Microsoft's website)

Step 1: Open Microsoft Authenticator

Open the Microsoft Authenticator app on your phone and select your Fullerton College work or school account.

Step 2: Start Passkey Setup

Look for the Create a passkey option and follow the on-screen instructions.

You may be asked to verify your identity, enable your phone's screen lock, or allow Authenticator to be used for passkeys.

Step 3: Follow Your Phone's Instructions

Continue through the prompts to finish setting up your passkey.

The exact steps and settings vary depending on your phone and operating system. If the instructions differ from what you see, use Microsoft's official guide below.

Step 4: Confirm Setup

Complete the remaining prompts and confirm that your passkey has been added.

If you don't see the option or setup fails, don't remove your existing sign-in methods. Contact ACT for help.

(Use this guide for detailed instructions and device-specific settings.)

• Your phone matters. Authenticator passkeys require a supported device and operating system. Not every phone that runs Authenticator can create a passkey.
• Authenticator alone isn't a passkey. Having the app installed or using it for verification codes doesn't mean you've registered a passkey.
• A new phone may require setup again. Passkeys created in Microsoft Authenticator are tied to that device and don't automatically transfer to a replacement phone.
• Keep your existing sign-in methods. Don't remove a working method until you've confirmed your new sign-in method is set up and working.
