This article explains how to add friends on Steam through the Steam website, desktop app, and mobile app by sending a friend request that your friend will see the next time they log in to Steam. You can also add friends by sending an invite link.

The Steam desktop app is nearly identical to the Steam website, so you can add friends with whomever you prefer. The Store tab in the app corresponds to Steampowered.com, Steam’s online store. The Community tab corresponds to Steamcommunity.com, Steam’s online community portal.

Here's how to find and add friends on Steam via the desktop app or the Steam Community website:

Open the Steam desktop app or go to Steamcommunity.com.
