How to log in Mac OS High Sierra with a blank password?

I just updated my old MacBook Pro 2012 to High Sierra. Tried to clean install. The file seemed to be corrupted. So I restored the Mac from a TimeMachine Backup. Now to log in, I need to type a password. The password is no password (it's blank). On the other OS, I was able to just click on the session picture to log in. Now it's asking me for a password. I left a hint: The hint says, no password. It's literally a blank password. Nothing. I tried to press enter... I just can't log in.


Any help would be greatly appreciated.


Note that I also tried to log in in safe mode, but that din't do anything.

Replying to myself, if ever someone have the same issue: I pressed CMD or CTRL or Fn or SHIFT and I got to where you can type the user name or password. Clicked back then I was able to just click on the session picture to go in.
