Log On Issues

I have previously set up a user (myself) as a backup for testing.  I have not used this user access for some years, so forgot my password.  I was able to generate a link for the password forgotten part but now fail at the 2FA page.  At the time I created this test user, there was no need for 2FA or that was not implemented yet, so I don't have that info. I also don't have recovery codes or the ones I previously downloaded are not 24 characters (mine are 8 only and I don't know if they are user or company specific).

I can still access the file via my prime access which also has 2FA, so I am not stranded but how can I reactivate that old test account? Before handing over the company file to new colleagues, I want to make sure everything works as it should.
