If you’ve been playing TERA Online for a long time now, chances are you’ve encountered the infamous user authentication failed error message. Truth be told, no matter where you get this error, it can really throw you off.
Much so if you’re just trying to get your daily dose of relaxation from TERA Online and discover that you’re suddenly unable to do so.
Fortunately, this error is not exactly rare, and there are a lot of TERA Online players who’ve experienced it at least once before. This doesn’t just mean you’re not alone in this, it also means there are a few fixes worth checking out.
What is TERA Online?
TERA Online is an MMORPG released quite a while ago (2011 was its initial release in South Korea). It had a bunch of closed and open beta testing sessions before the official release.
The game has regular MMORPG features such as PVP, crafting, and questing, and uses a non-target battle system. This means that instead of clicking the target and selecting things to hit them with, you just fire away as you would in an action game.
More so, you’ll need to be quite skillful, considering that you’ll have to dodge enemy attacks actively. That’s TERA Online in a nutshell, although we skipped a lot of awesome features.
We’re not here to talk about TERA, but we can (hopefully) help you fix the user authentication error in the next few following sections.
How to fix TERA restricted account sign in error?
1. Try using a VPN
- Purchase a premium VPN subscription (we recommend Private Internet Access)
- Download the VPN installer on your PC
- Install the VPN client on your computer
- Launch it and connect to your account
- Select a fast server (nearby servers are faster)
- Launch TERA Online
- Check if the problem still persists
The usability of a VPN in such issues has been widely debated. The general consensus is that more often than not a VPN will do the trick, as it does with many other connectivity issues.
Private Internet Access is a Kape Technologies product and also one of the few VPNs that offer 24/7 live chat support.
Note that if the VPN fix doesn’t work, you shouldn’t give up just yet. Disconnect from the server you chose, connect to another (preferably fast) one and try again.
Private Internet Access
Getting the User Authentication Failed error in TERA? Private Internet Access could help you fix this issue.
Network congestion is usually a quite decisive factor that determines the occurrence of connectivity issues. Thus, if the VPN server is overcrowded, you may want to try another one.
2. Try logging in with Facebook
Reportedly, users noticed that logging into their TERA Online account through Facebook seemed to work. Just use the game launcher and instead of logging into your TERA Online account, use your Facebook account to perform the operation.
However, for this fix to work, you’ll need your TERA and Facebook accounts to be linked. This can be easily achieved on the Account Settings page on the TERA Online website.
Long story short: make sure your Facebook and TERA accounts are linked, then try to log into TERA with your Facebook account.
3. Avoid logging from multiple accounts
Apparently, TERA Online has this 24-hour block that applies to users who try logging in from several accounts on the same machine, in a short interval of time.
To prevent that from happening, only stick to one or two accounts. As far as we know, there’s no limit to log-in attempts from the same account, as long as you don’t switch IP addresses frantically between attempts.
Also, it would be a great idea to check if you were banned. Many users mistakenly believed this error had something to do with their bad connection when in fact, their accounts were in fact inaccessible due to bans.
Final thoughts on fixing TERA user authentication error
All in all, if you’re trying to log into TERA Online and receive the user authentication error, don’t panic. There are a few reasons why this could be happening, and a bunch of fixes for these reasons.
First and foremost, you should make sure that your account is not banned. Else, trying any of the fixes might be completely useless.
One of the most popular fixes for this issue is using a VPN. If using a VPN seems to be in vain, try switching servers between ditching this suggestion. It could save you a lot of time and hassle.
Last, but not least, you could try logging in with your Facebook account, as suggested by various users on the TERA Online forums.
