An apparent leak has exposed the phone numbers and texts of millions of Steam accounts, but account security wasn't compromises.

The leak consisted of old text messages containing one-time authentication codes that had all expired. These were linked to the phone numbers they were sent to, but the phone numbers were not linked to any account details.

Steam users may be at risk as a reported data breach exposes 89 million account details. Users are urged to change passwords and enable two-factor authentication.
