Keyoxide allows you to prove “ownership” of accounts on websites, domain names, IM, etc., regardless of your username.
When you visit someone’s Keyoxide profile and see a green tick next to an account on some website, it was proven beyond doubt that the same person who set up this profile also holds that account.
