many thanks to everybody for your helpful replies; chroot and resetting the user's password worked and saved me a lot of time. Thanks also for teaching me something new (and implicitly making clear how limited the standard password 'protection' is and that one should use an encrypted file systems if one wants the data there to be private ;-). I didn't try the root-access based methods as I thought that I didn't have that access anymore (as I had messed up the password of the only user); but afterwards I realized that the root password hadn't changed from the factory settings and so that would have been an even easier route.
Check that you can access as root. By default, root has the same password as the 1st user (something I never do). -- Cheers / Saludos, Carlos E. R. (from oS Leap 15.3 x86_64 (Erebor-4))
