Possible to protect local data with password in client?

Hi, I’m just checking if nextcloud can be a solution for my home office. I understand that it’s easy to use the webclient and so make sure that only somebody with password can access the data on the server.

Would be super nice of course to use desktop client and integrate cloud data into “normal” file explorer. But I share my private Laptop with other people, so it’s no option to just have easy accessible local data on it.

Question: is it possible to use the client ONLY with a password each time you start it? so that files can only be seen while logged in? And when you logged out that you cannot see/open the files?

Thank you very much in advance for answering…
