I have a steam deck an I love it, but I don’t think using it as a laptop is a good idea. Unlocking a steam deck doesn’t need a password (by default), just like Switch, GameBoy or PS Portable. If steam deck is lost, sensitive personal data can be accessed easily. Besides, I’d expect a higher risk of losing a steam deck, as I’d been playing it on various places like metro or train stations.
If you never take your steam deck out of your home, then it sounds sensible to use SD as a laptop
I’m sorry that I don’t understand it.
By default, all windows/mac/linux laptops will ask users to set up a password for log-in. This is not sufficient, but much better than password-less unlock
