Clean install (no upgrade) Hassos won't let me in

Continuing the discussion from 0.77: Authentication system :policeman:‍♂ + Hangouts bot :robot::

created a clean and new install on a second Rpi3B+. created a user account on the first screen, and trying to login with that on the second screen. Invalid. No way to go back, no way to get into the sd card, because I havent yet installed Samba or SSH.
Now what?
Any help is much appreciated

pull the SD card and mount it on your laptop/PC. delete the file /config/.storage/auth
What have ya got to lose?

can’t be read on my Mac…

just to know I didnt do anything wrong: I should use the chosen login and password from the first account create page, on the second login page?

That seems reasonable.

Username and Password are both Case Sensitive

yes thank you. Ive managed for now by reinstalling the image, but I would think another way to be available…?
