I changed my PW and i had to enter the Backup Codes. Thats ok bc i had 2F activitated.
First i changed my PW on PC and could copy the codes from my phone - easy.
Then i was naturally logged out of my phone, and as i tried to get back into it NO code i tried was accepted. "Two face authentification code wrong."

I used them all. Then created new ones. Not one was accepted as correct. I even copy pasted them, not correct. I logged into the browser, same issue - no code was accepted.
Eventually i deactivitated the 2F option on my PC application and could finally login via browser and phone app. But the point of the 2F should not be that it nearly makes me lose my account alltogether.
So either its way too complicated and i somehow messed up, or it failed to work right?
