• You can link from the ESO Account Website or after selecting Play on The Elder Scrolls Online in your Steam Library and selecting “I have an existing PC/Mac Elder Scrolls Online account."
• If your version of The Elder Scrolls Online was not purchased through Steam, you will not be able to link your Steam account to your existing ESO account without purchasing a new copy of the game on the Steam platform first.
• If you are not prompted to link your account when launching ESO for the first time, you should temporarily disable any firewalls or antivirus software you have and try again. Once your accounts are linked, please remember to re-enable your security software.
• Note: Only one ESO account can be linked to a Steam account.

Your Steam account will now be linked with your ESO account! You can now log into the game and play by simply launching the game from your Steam Library.
