Internal password authentification doesn't work

Hello everyone,

When I try to generate a QR code via the drop-down menu on my profile, or via Personal Settings → Security → Create App Password, a pop-up window appears asking for a password to authentificate myself for this action. Unfortunately, my login password is always rejected as ‘incorrect’ at this stage.

Is this issue already known?
