Hi, My pet charity has 5 wee HP laptops.

They were all set up using the same Microsoft account.

Our thinking was when it came time to change the password, we would only need to do it on one device, and the other 4 would automatically follow suit.

Zoom ahead a few months, and now one of them is saying "incorrect password", while all the others are happy as.

(These are communal devices, anything could have happened to it. I hear rumours Win10 was reset on it.)

I'm 100% certain we are typing in the same credentials that the other 4 devices are using. 

Was my initial assumption incorrect? Can they use the same account but each have a different password?

For now I have switched the device over to using a local account (how I was allowed to do that without correctly entering the MS password I do not know).

When trying to switch to the MS account , and failing, it gives an option to "recover the account" , but what effect will that have on the other 4?

Any help would be most appreciated, thank you.
