Yes, to view all sharable links you have created, do the following:
1. Log into your account.
2. Click on the user dropdown in the top right hand corner of your screen and then click on the 'Manage share links' dropdown.
If you do need to completely disable a link, you can do so there.
Just find the link you need to disable and hit the red button to completely remove any access via that link. If you make a mistake you can also reenable it at any time.
Note: Remember that links can also point to a group of videos and images, so if you shared three of them at once, disabling the link will cancel access to all of them.
