One of the best horror titles from last year was Phasmophobia. An early access game developed by a single person that became an online phenomenon, and the go-to horror game for co-op. The title is still in its early access state and will continue to remain in it till the developers work out bugs, technical problems, and add more content. Now, if you are on PC, and are running into the Phasmophobia Steam Authentication Failed Error, here is how you can easily fix that.

We have extensively covered Phasmophobia, and have written various guides on it to help out players that are running into these problems. Also, some people might assume this is a VR-only title, but that is not the case, and you can easily play it without a VR-headset on PC.

A few folks have reported that they are running into this error while running the game. The game launches fine, but this error shows up in-game, and because of that, players can’t actually play the game online. There are a few things you can do to fix it, however. Again, these issues will be frequent for a while, given how the game is in an early access state, and hopefully, when it launches with the 1.0 version, everything should be running smoothly, and the bugs are ironed out.

Regardless, here are a few things you can try to mitigate your current situation, and get back in the game. These solutions are provided by the developers, and moderators for the title itself.
