Your LinkedIn URNs.
Sign in with LinkedIn. This page shows your person URN and the organization URN of every Company Page where you hold a role. That is all it does.
This page does not store any data.
It reads from LinkedIn once, shows the result in your browser, and forgets it when you close the tab. There is no database, no log and no export. Nothing is written to LinkedIn.
Permissions requested on LinkedIn's consent screen: openid profile r_organization_admin — all read-only. A Page is shown only to people who hold a role on it.
