I did that (provide a false answer) with a yahoo mail account and got myself locked out forever... when they introduced the security questions it was a measure to double check when changing the password. as i was using a password manager i just provided nonsense and didn't store it anywhere. years later yahoo decided to make it mandatory to enter the security question when logging in from a new device. no chance to get in there anymore...
