Also, they should be able to use their account even without having to understand anything about it; guides and tutorials will be available if they want to explore other blockchain services, but they should be absolutely not necessary to start when joining
I think you need a basic understanding of the 5 passwords to do anything on the site.
If you don't save them it's game over before it begins. From someone new to crypto and used to blogspot or medium it'll be odd to go from 1 login to more than one for different actions.

It's true that the Master Password is always to save.
But even the concept of the 5 passwords (adding posting, memo, active, owner) and even adding 4 more (with the public, and the private ones) is a whole confusing lot to understand for anyone new.
That is the reason why services which "act as container for all this" (like keychain) are essential, in my humble opinion!
