Zorin OS should have an option in the settings to activate a guest account.
Maybe there is already a guest account system (usable in terminal), and if it exists it should be added to the settings.
A guest account gets reset when you log out (home files deleted, app data deleted...)
This could be useful in case you need to share your PC to a friend for some minutes, and using a guest account instead of creating an account then deleting it is simpler.
Yeah, but the guest account could be disabled by default, and activated with a switch in settings if needed. Linux Mint has a gust account, and its disabled by default, but it has a switch in the settings.
Just to say a thing, if a guest account is needed just some times it's fine to simply create a normal account and then deleting it later while if it's needed more often it's reasonable to install another service that has this feature.
