Developers are not limited to Steam's CEG and may include other forms of DRM and other authentication services than Steam; for example, some games from publisher Ubisoft require the use of their UPlay gaming service, In September 2008, Valve added support for Steam Cloud, a service that can automatically store saved game and related custom files on Valve's servers; users can access this data from any machine running the Steam client.

In May 2012, the service added the ability for users to manage their game libraries from remote clients, including computers and mobile devices; users can instruct Steam to download and install games they own through this service if their Steam client is currently active and running.

In September 2013, Steam introduced the ability to share most games with family members and close friends by authorizing machines to access one's library.

By 2019, the service had over a billion registered accounts with 90 million monthly active users.

With an update to the Steamworks SDK in March 2009, Valve added its "Custom Executable Generation" (CEG) approach into the Steamworks SDK that removed the need for these other measures.

The CEG technology creates a unique, encrypted copy of the game's executable files for the given user, which allows them to install it multiple times and on multiple devices, and make backup copies of their software.

Valve decided to create a platform that would update games automatically and implement stronger anti-piracy and anti-cheat measures.

Through user polls at the time of its announcement in 2002, Valve also recognized that at least 75% of their users had access to high-speed Internet connections, which would grow only with planned Internet expansion in the following years, and recognized that they could deliver game content faster to players than through retail channels.
