If you’re having problems logging in, you may need to reset your password. Additionally, you may be having issues with your email verification. Either way, the site to go to is https://vrchat.com/home. At this site you can reset your password or change your email address. Please note that you can log into the VRChat.com site using either your email address or your VRChat account name. Once you've logged in, you can change your password as well as change your verification email if you misspelled it.
If you get "Authentication failed" or “Invalid Credentials”, it means your password or email has been entered incorrectly. Use password recovery to get it back. This may potentially also indicate that the login servers are under heavy load.
Finally, if you’re waiting on a verification email, please be patient! Our system is under heavy load and it may take some time to verify your email.
If you’ve been waiting for a long time for your verification, please email firstname.lastname@example.org from the address your VRChat account is registered under, and include your VRChat account name.
