Black Desert Online Account Authentication Failed
The Black Desert Online Account Authentication Failed error is by no means new, having been plaguing players of the MMORPG for a while now.
The Black Desert Online Account Authentication Failed error usually pops up when attempting to log in, but it can happen in a number of scenarios. Players are reporting encountering it when attempting fresh logins, but also after being kicked out of the game for various reasons.
The developers pin the Black Desert Online Account Authentication Failed error on the game client detecting that a player's authentication key is no longer valid. The suggested steps for fixing the issue when using the web launcher involve logging into your account, pressing the wrench button on the right side of the launcher, clicking the Recovery button and launching the game.
If you're playing via Steam you should head to your library, right click on the game and select Properties. From there, click the Set Launch Options button under the General tab. A new window will pop up and you'll want to add --licenseRecovery=TRUE into it. Click Ok, then boot up the game. It's also worth deleting the ads and cache folder in your installation directory, the cache folder in your documents and the following temporary folder C:\Usersusername\AppData\Local\Temp.
