Disable Facebook Login
If you’ve logged into your Weebly account through Facebook and decide you no longer want to do so, you can disable this in a few short steps.
First, log in and go to your account page.
Click the Manage Account link, then on “Connected” next to Facebook. You’ll be asked to Disconnect in a pop up, so go ahead and click that. Don’t forget to save in the Manage Account window when you’re done making changes.
Head over to your Facebook account next, and click the arrow in the upper right to access the Settings page.
From there, click on Apps and Websites in the left sidebar and locate Weebly in the list. Click the tick box to the right of the icon and use the Remove button to completely disconnect Weebly, or click on the “View and edit” link to make changes to the permissions.
You should be all set after that, and if you change your mind you can always set up Facebook login again by clicking the Facebook login button at the sign in screen.
