Logging in is fun to do. And you can do it with Facebook, Google, or even Amazon. Here’s the secret.
Click on the My Account tab from the lower left-hand side of the nav bar.
Once you’re in your account dashboard select Account Details from the upper left-hand menu.
Then scroll down to the bottom of the page where it says, Social Login Accounts, and click on “Connect one now.”
Then select either Facebook, Google, or Amazon and follow the instructions. For this example I'll select Facebook.
That’s it, you can now login with your Facebook account. :)
