Steam Guard is Steam’s two-factor authentication (2FA) system. It adds an extra layer of security to your account by requiring a special code each time you log in from a new device.
Option 1: Steam Guard via Email (Basic)
- Open Steam and go to Steam → Settings → Account.
- Click “Manage Steam Guard Account Security”.
- Select “Get Steam Guard codes by email”.
- When you log in from a new device, Steam will email you a code. Enter it to continue.
Option 2: Steam Guard Mobile Authenticator (Recommended)
- Download the Steam Mobile App on your phone (iOS or Android).
- Sign in to the app with your Steam credentials.
- Tap the menu icon and go to Steam Guard.
- Tap “Add Authenticator”.
- A verification code will be sent to your email. Enter it.
- You’ll receive a recovery code — save this somewhere safe. You’ll need it if you lose your phone.
- The app will now generate time-based codes. You’ll enter these whenever you log in from a new device.
Why enable Steam Guard?
- Protects your account from unauthorized logins.
- Required to trade items on the Steam marketplace without a 15-day hold.
- Required to use the Steam Community Market without trade restrictions.
- Adds a 7-day cooldown on any further changes once enabled, preventing quick account theft.
Tips
- Always save your recovery code in a safe place.
- If you switch phones, remove the authenticator from the old phone first, or use the recovery code to transfer it.
- Steam Guard via the mobile authenticator is significantly more secure than email codes.
