Steam Security

Secure Your Steam Account
Complete Guide for 2026

Your Steam library is worth hundreds — maybe thousands — of dollars. Steam is the #1 target for gaming account hackers. Here's how to lock it down.

Steam Guard API Key Protection Protect Your Library

Steam Security Checklist

Enable Steam Guard Mobile Authenticator

This is non-negotiable. Steam Guard adds a rotating code from your phone to every login. Without it, a stolen password = stolen account. Install the Steam app → Steam Guard → Add Authenticator.

Check Your Steam API Key

Go to steamcommunity.com/dev/apikey. If you see a key you didn't create, revoke it immediately. Scammers use stolen API keys to intercept your trade offers and redirect items to their accounts.

Deauthorize Unknown Devices

Go to store.steampowered.com/twofactor/manage and deauthorize all devices. Then re-authenticate only your current devices. This kicks out anyone who may have access.

Check for Breach Exposure

Your Steam account email may have been exposed across dark web sources. GalaxyWarden's DoxxScan maps your identity chain across 700+ dark web sources and shows exactly how your data is exposed.

Review Payment Methods

Remove saved credit cards if you don't make frequent purchases. Consider using Steam gift cards instead of linking payment methods directly.

Verify Email & Phone

Confirm that the email and phone number on your Steam account are current and yours. These are your lifeline for account recovery if anything goes wrong.

Know Your Steam Library's Value

GalaxyWarden's Steam integration shows you exactly what your library is worth — so you know what you're protecting.
