So I got an email today saying that my riot ID "updated" (I guess it means changed?) which is something i didn't do
So i launched the game and expected it to just go straight into the game because i have auto login enabled but instead it took me to the login screen
I tried every combination of passwords I could think of but still couldn't login so I thought i tried to reset my password and I need my username for that
So I put my username with the region i play on and got no email then I tried every other region. same. no email
Then I tried recovering my username. AGAIN got no email. After that I decided to create a new account with the same same email and username as the original and it said that the username is already taken so I guess a wrong username wasn't the issue. I finished creating the new account with the email of the original one (different username now) and finished successfully so I decided to check if the username and password recovery were what's broken and now they worked perfectly fine and I got the emails for them but there was no mention of the original account that i'm trying to access
I also tried the "account recovery" feature and same it says my username doesn't exist even when used with every region
I also found this Reddit post where OP is having the exact same issues https://www.reddit.com/r/VALORANT/comments/g21rfn/valorant_your_login_credentials_dont_match_an/
