Exactly. It's one or the other but not both at the same time.
If you try to log on with the new password later, Windows will connect to Microsoft's online server for syncing and verifying your login credentials. After successfully login, the old password automatically expires and you can't use it to log on any longer.
firstname.lastname@example.org password ispemailpassword. When I signed up for my live ID I used email@example.com and password idpassword. My Live ID password can be anything I want it to be, it does not have to be the password to the e-mail account your using. Unless your using an actual Microsoft e-mail account. I can go in and change it any time I want too. It has no effect on my e-mail account, one has nothing to do with the other. When I setup my live ID I got a confirmation e-mail with a link to verify I'm who I say I am. Same as when you signed up for 10 forums. If your using a Microsoft e-mail account its different though, they are linked.

Especially on a shared computer the use of an MS Account and OneDrive is really not only practical and recommendable but also the safest possible way to store your personal data. All users saving everything on local hard disk, that is about the dumbest you could do! A total security nightmare!
An admin user, be it your dad or mom or brother or whatever, an admin user can always access all data stored locally. You teenager, if you think your parents won't see you locally stored emails and pics and stuff, I am sorry but you are wrong.
But: If you had an MS Account and stored your stuff online, not syncing it to local computer, they had no way to know what you have there. Plus: you could access it from any device.
A bit absurd when you think of it: this tinfoil hat brigade won't use a safe method, OneDrive and an MS Account, but instead tell us all to use the unsafest of all data storing methods, store everything locally on a shared computer.
The sign-in method is not the reason for the MS Account. Sign-in is about the only thing in Windows 10 where it's totally irrelevant which type of account you have.
I could not live without an MS Account and OneDrive, the best example of the usefulness of an MS Account. All data, I mean absolutely everything I have ever created, saved or edited on any of my computers will be automatically saved on OneDrive. I write a memo with Word on my laptop, save it, go to the city and Starbucks, open the same document on my Windows Phone while sipping my espresso, fly to Luxembourg and using my tablet print that memo on the hotel's printer. Using three devices, without a need to think on which device my document is. Any device, I click Open and I can see all my documents.
I don't have to remember to take that particular laptop or this tablet with me when I travel or simply go to city for coffee because absolutely everything I have, absolutely everything I save and modify and download is always accessible from any networked device everywhere in the world.
An added bonus: as often happens, one evening my PC suddenly dies. Of old age, of virus, whatever the reason. I am totally, completely, profoundly absolutely OK with it because I only need to get to any other networked Windows, Android, Linux, iOS or MacOS device and I can access everything I have. I never lose a single file, a single contact, a single email, a single photo, a single favorite website.
Esteemed tinfoil hat brigade, I feel sorry for you.
