Can I configure GateKeeper using Windows Hello and a PIN?

No, Windows Hello and PIN can not configure GateKeeper because when you add a user, you need computer login information which includes the computer's domain name/username/password. However, if you set up your computer to Windows Hello and PIN, you don't know the computer's password so you can't configure GateKeeper with Windows Hello and PIN.

If you don't know the Windows password, create a new local account

 - Open the settings page from your computer.

 - Click account then click Your info.

 - Under there, click sign in with a local account instead.

 - You are creating the local account.

After creating a new local account, log in with the local account (use local password to log in)

 - Open the command prompt by pressing cmd from the search bar.

 - Type Whoami to verify the domain name and username.

 - Open your GateKeeper Hub and under the user, add a new Win Local account using the information you got from the command prompt. (Domain should be all CAPS).

 - After you add credentials under your profile, lock the computer and type your PIN to log in with GateKeeper. You're done.
