User Authentication Failure
If you are seeing "User Authentication Failure" when signing in, this means you are unable to access the game servers.

This message will display for the following reasons:
You are in a physical location that is restricted from accessing game servers.
Your account has been blocked for participating in or being related to actions that have violated the Terms of Service.
You have accessed an excessive number of accounts within a 24-hour period. This will resolve after 24 hours if you do not attempt to log into more than six accounts in that time.

I heard that you might be able to bypass the user authentication error by logging into TERA via Facebook (on the launcher), but you'd need your account connected to your facebook in order to do that. (Account Settings on the TERA Website) If it doesn't resolve in this time frame, I suggest you contact support to help you regain access to your account, my apologies.

You can get this message for a variety of different reasons and they don't all require a 24-hour wait as far as I know. The 24-hour wait is usually for cases where you've logged into too many different accounts on the same machine; in that case, going back to one of the earlier accounts would work until the time elapses. If not that, this error could also be in case your account is banned for whatever reason, which obviously won't clear until the ban is up -- check email for that. Otherwise, if it is because you were connecting from a forbidden region, I tend to think that would clear up once you're not longer connecting from that region. I know that on some occasions when a VPN wasn't working I'd get an different error on launch, and just changing/rmoving the VPN fixed it.

nah didnt log in multiple and also didnt receive any sort of ban or suspension email or message. This happened while i was playing another game with VPN and forgot to off it before turning on tera launcher and when i realised and off the VPN, it continues to give me the error almost 14h now.
i'm a U.S Citizen and I used a VPN on an EU region to test if i can play on TERA Na on EU region. After that i disabled my VPN and comeback to play with my account and i got the error User Authentication failed it seems that their stupid IP block system depends on your IP address which changes whenever you restart your modem i just paid my sub and i got this [filtered] [filtered] thanks ENMASSE you [filtered] Give me back my money you assholes your [filtered] system blocks anyone that has a VPN and your term of service doesn't mention personal use of VPN and and my Region is not locked again I live in the U.S
