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

If you've recently received any one-time password text messages that you did not request, ignore them and change your password again. In the coming weeks, keep an eye out for any phishing attempts disguised as game product offers or other Steam-related content.

Valve says the leak features phone numbers that previously received a one-time passcode, but they're not associated with a Steam account, password, or other personal data.
