I don't know if I missed something, but i'm using the PlayFab account Authentication method, so I register my users with RegisterPlayFabUser using email, username and password, and then when I try to login with LoginWithPlayFab using username and password, it doesn't matter if the password is correct or even if it's just one character it still logs in successfully, like if it only checks for the username and the password can be whatever.
I really don't know what's going on, hope you can help me.
