Is this possible in any way?

-If you knew someone's gmail password but they ended up changing it and you didnt know what it was but you end up changing it again just to check something, but you dont want that person to know that you did that.



Is there some kind of way you can go back and change their password back to what they had it without changing the password again because you dont know what it was when they changed ityes it's possible.
I think it is possible. Look it up on Google.
