Why Can’t I Log Into My Account?
As of 2017, ShareThis has deprecated from the use of legacy accounts (publisher keys) in order to gain access to share buttons. We have since introduced our brand new platform that allows you to keep track of your custom share buttons via platform login. Feel free to re-register using our brand new platform and additional tools by signing up here: http://platform.sharethis.com/get-share-buttons
We also have a FAQ related to the change that you can find here:
If you have any additional questions please be sure to let us know!
