How to fix VAC Authentication Error in CS:GO
Best answer
TechGuru89
Restarting your computer is the classic turn-it-off-and-back-on approach that surprisingly resolves the VAC authentication error most of the time. If that doesn't work, try verifying the integrity of game files in Steam: Right-click CS:GO in your Steam library > Properties > Local Files > Verify integrity of game files. This method checks for any missing or corrupted files and fixes them. Also, ensure your antivirus isn't blocking any of the game's files!

Disable any unnecessary third-party software before playing CS:GO. Some programs interfere with VAC and cause authentication errors. Stick to the essentials!

Make sure to run Steam as an administrator! Right-click on the Steam shortcut and select 'Run as administrator.' This simple step often fixes the VAC authentication error by giving Steam the necessary permissions to operate correctly.

Just uninstall and reinstall CS:GO lol. Worked for me every time I had weird errors like the VAC one. Plus, it's a good excuse to take a break and chill while it reinstalls.
