Teams - can automatic sign-in be disabled

We have several meeting room computers and shared laptops which have a single shared user account (and they are not domain joined). Is it possible to prevent Teams from signing in automatically? From testing, it appears that once the user clicks OK to the default options the first time they sign in, it will then cache the details and even if they sign out, it will remember the password as soon as an attempt to sign back in with that email address is attempted - which is obviously not suitable for a shared computer account.

Thanks

    I posted the original question - never did find a solution, and we have moved away from having any shared accounts (this was one of the reasons). As stated by the most recent commenter, the suggestion by JimmyYang is wrong - even if a user signs out, it doesn't forget the cached credentials and they can sign in again without being asked for the password.

    MFA is also of limited use, as if shared devices are in an office location it may well be the case that the office is on a whitelist so that MFA isn't applied there.

    Hi!

    Did you choose the option to cache the credentials when you firstly login in Teams?

    If you don’t want to login in Teams without enter credentials, you can try to right-click the app icon in their taskbar, and then select Log out. Once they've sign out of Teams, they need to enter their credentials again to launch the app.

    In my experience, Modern authentication is a process that lets Teams know that users have already entered their credentials (like their work email and password) elsewhere, and they shouldn't be required to enter them again to start the app.

    Besides, you can try to enable MFA for your organization:
