Steam Guard is an additional level of security that can be applied to your Steam account. The first level of security on your account is your login credentials: your Steam account name and password. With Steam Guard, a second level of security is applied to your account, making it harder for your Steam account to fall into the wrong hands.
When Steam Guard is enabled on your account, anyone attempting to login to your Steam account from an unrecognised device must provide additional authorization. A special access code will be sent to your contact email address, and this code must be entered into Steam before your login is complete.
Once you've verified your email address with Steam, Steam Guard becomes available for your use after restarting Steam twice. Once enabled, you will be required to access your email and provide the special access code from Steam Support when logging into Steam from any device which we don't recognize.
Steam Guard is enabled by default on your Steam account if your email is verified and you have restarted Steam twice since verifying your email. If you have disabled Steam Guard, and wish to reactivate it, please follow the instructions below:
That's it! With Steam Guard enabled, you will be asked to enter the special access code sent to your email address each time you login to Steam from an unrecognized device.
No, there's no limit. Steam Guard is aimed to protect the value that is yours, not limit your access to your stuff. As always, you can access your Steam account and library from as many machines as you'd like.
Exit Steam and log back into your account. This will generate a new verification email.
Ensure that you enter the most recent code sent to you - older codes will not work.
Please check to make sure that you are accessing the email address that is registered to your Steam account.
If you do not receive the e-mail at all, check and make sure it is not being filtered as spam.
Please try adding "firstname.lastname@example.org" and "email@example.com" to your contacts or trusted senders list within your email client and request a new access code.
Even though Steam instantly sends an email, you may encounter a delay with some email providers depending on their server load and processing times. Please contact us if you have not received the verification email after 3 hours.
