How Do I Prevent User Profile Removal @ Sign in Screen : Chrome Enterprise

OK there is a workaround to prevent this insane default behavior though Google does not encourage the workaround (even though a bug was filed years ago and users are screaming for a fix.) The workaround is Never show user names and photos

From the docs:

Sign-in screen

Specifies whether the Chrome device's sign-in screen displays the names and pictures of users who have signed in to the device.

Displaying the names and pictures of users on the sign-in screen allows users to quickly start their sessions and works best for most deployments. We recommend you change this setting rarely and selectively to ensure the best user experience.

• Always show user names and photos—Lets users choose their user account on the sign-in screen (default).

• Never show user names and photos—Prevents user accounts from being displayed on the sign-in screen. Users must enter their Google Account username and password each time they sign in to their Chrome device. If you have SAML single sign-on (SSO) for Chrome devices and send users directly to the SAML identity provider (IdP) page, Google redirects them to the SSO sign-in page without entering their email address.

  Note: If users are enrolled in 2-Step Verification, they’re prompted to perform their second verification step each time they sign in to their Chrome device.
