Ensure the option to remain signed in is hidden
설명
The option for the user to Stay signed in, or the Keep me signed in option, will prompt a user after a successful login. When the user selects this option, a persistent refresh token is created. The refresh token lasts for 90 days by default and does not prompt for sign-in or multifactor. Allowing users to select this option presents risk, especially if the user signs into their account on a publicly accessible computer/web browser. In this case it would be trivial for an unauthorized person to gain access to any associated cloud data from that account.
