Data Stored on Logic Board

[Barney63]

I've just had the logic board replaced on my rMBP and noticed since I've had it back there have been a few passwords that I've been asked for again. I also had to go through reactivating Parallels (although the key auto filled).
All my data, browsing history emails etc all seem to still be there, and they didn't mention doing anything to the SSD.
Is some data stored on the logic board?

I'm not aware of anything being stored on the logic board.

Some Applications use a machine key when you register/activate them. If you change a hardware component they will notice a change in the machine key and ask you to re-activate. That might be the simplest explanation.

The only info stored on the logic board is the EFI info and the serial number of the machine. None of your software settings or passwords (unless you have an EFI password) are stored there.

I've just had to input another password, this time for sending an email.

That's browser and/or software preferences that were reset after the logic board replacement. It's a normal occurrence.

So did the Apple Store reset them? Why?

No, you have a new logic board with a different "serial number"/ID and apps and/or keychain access can tell you have a "new" computer and they want to make sure you are you. It should clear itself up as you use it.
