This policy controls whether a user is automatically signed out of their previous session when they sign in to a new Google ChromeOS device.
Setting the policy to Enabled will sign out the user from their previous session upon a successful sign-in to a new Google ChromeOS device.
Setting the policy to Disabled or not set will sign out the user from their previous session only if either FloatingSsoEnabled or FloatingWorkspaceV2Enabled policies are Enabled.
