I want to manage or revoke access tokens I have granted to 3rd party Stack Apps, but I have a hard time to find them in the UI.
Go to your profile: https://stackapps.com/users/current
Click the "Edit Profile & Settings" tab: https://stackapps.com/users/edit/current
Click "Applications" on the left sidebar (no handy universal link for this, but it'll take you to a URL like
https://stackapps.com/users/apps/53175where 53175 is your user ID)
And there you'll have your list of authorized apps, with a little "remove" link next to each.
