Login with Facebook allows external websites like Quizlet to use Facebook's login system. Instead of creating a Quizlet account by entering your email and password, everything is done automatically with one click.
There are also additional features when you login with Facebook:



If you have registered for Quizlet with an email and password but have not linked your Facebook account, go to the Preferences page and click "Link with Facebook."
You can unlink your Facebook account at any time. Go to your Preferences page. Make sure you have added an email address and password so you can still login after your unlink Facebook. Then click "Unlink Facebook Account."
If you see a message that says “Unable to load Facebook” with a link to this page your computer didn’t successfully load the Facebook login system. The likely reason for this was just a bad internet connection at the time.
Please clear your browser’s cache, refresh the Quizlet home page, and try again. If the problem persists after doing this, either Facebook’s servers are having problems or your network is blocking access to Facebook. Contact your network administrator about this issue.
