Your Steam username is the display name other players see when you're gaming, but it's separate from your account login credentials. Finding it matters when you want to share your profile with friends, join communities, or troubleshoot account issues. Steam stores this information in your account settings, and there are several straightforward ways to locate it depending on where you're accessing Steam.
These articles walk through finding your username on different devices and platforms—whether you're at your computer, on mobile, or looking at your profile page. You'll also learn the difference between your username and other account identifiers like your account name or friend code, so you know exactly what to share and where to find it when you need it.
