STEAMID I/O: convert steamIDs, steamID64s, steamID3s, customURLs and find Steam Community profiles.
A steamID is a unique identifier used to identify a Steam account. A steamID can be converted to the newer steamID3 and to a steamID64, sometimes referred to as community ID or friendID. With this steamID64, a user's Steam community page can be found. A customURL is an optional, more personalised identifier to look up a user's Steam Community page with.
Signing in through Steam gives you the following options and features:
- show/hide a Steam user's avatar
- show/hide a Steam user's location in an embedded OpenStreetMaps frame
- export of list output for use in SourceBans
- enable/disable autofocus on the input form field
- post feedback
Signing in through Steam is entirely safe. Only your community id is passed on to STEAMID I/O, for which a profile will be created. In this profile you can set said options to your liking.
If you no longer wish to keep your profile, you may simply stop using it or request to having it removed.
