Yesterday I changed my username against my will (had one username for 8 years)...
Today I get the message in the title.
Then... after thinking really hard... I thought I had it, but what do you know? YOUr loGin crEDenTIAls DON't matCH aN acCoUNT In OUr sySTEM.
So it has to be my password, I think. I go to the website and click forgot username because I remembered I didn't touch my password (don't get ideas riot) and I get a message that it has been sent to my email address.
That address was created more than 8 years ago and I haven't used it in about 8 years,
BUT RIOT READ THIS:
I logged in on my first try... because I didn't have to change it for some stupid security reason.
Was there no one in that room able of think of a better idea?
No heads up about the change?
How about logging in with your email address as your username?
Thank you for caring about my online safety
