Account Question

Has TechRepublic reset user account details or anything recently?
the last time i was on the site was a couple of weeks ago but when i tried to get in using my username/password i have had for years i was given a invalid login credentials page.

I also not my first name and last name have changed to a random selection of letters.
Was my account updated by techrepublic. I honestly can’t remember chaning my in account details and my password.
