I would like to Link my Steam to my VRChat account to make Logging in while in VR easier, however I keep seeing a lot of posts about people losing their data if they do it wrong. I don’t have many of my Avatar files any more due to things like lost media from broken drives and forgetful backing up and it would be really sad if I lost all of them. :(
For that just to be sure you can check the KB of vrchat official webpage https://help.vrchat.com/hc/en-us/articles/360062659053-I-want-to-turn-my-platform-account-through-Steam-Meta-Pico-or-Viveport-into-a-VRChat-account or the wiki page about it https://wiki.vrchat.com/wiki/Account_Linking
