In light of the recent abuse of the Streemian service, many people have been asking how to disconnect their account. A lot of helpful people gave them the link https://v2.steemconnect.com/revoke/@streemian.
But what if you want to revoke access to another site? Well, it's pretty simple. You can view a full list of all apps that currently hold your permissions at https://v2.steemconnect.com/login?next=/apps/authorized. Just find the one you want to remove and click "Revoke".
Hope that helps you out. Good luck!
