Follow Manager
This app talks to GitHub on your behalf. Nothing more.
Sign-in happens on GitHub’s own page. We never collect, store, or ask for your GitHub password.
The GitHub access token stays in an encrypted, HttpOnly cookie on the server. It is never sent to JavaScript in your browser, never put in a URL, and never logged.
GitHub → Settings → Applications → Authorized OAuth Apps → Follow Manager → Revoke. After that, this app cannot read or change anything on your account.
