  1. Go to Office.

    If you most recently used a passkey to sign in, you're automatically prompted to sign in with a passkey. Otherwise, select Other ways to sign in, and then select Face, fingerprint, PIN, or security key.

    Alternatively, click Sign-in options to sign in more conveniently without having to enter a username.

Known issues

Mobile device might be prioritized over security key

If you're using Chrome or Edge, the browser may prioritize using a passkey stored on a mobile device over a passkey stored on a security key.

  • Beginning with Windows 11 version 23H2, the operating system shows the following prompt during sign-in. Below More choices, choose Security key and select Next.

  • On earlier versions of Windows, the browser may show the QR pairing screen to continue with using a passkey stored on a mobile device. To use a passkey stored on a security key instead, insert your security key and touch it to continue.
