There are a few ways that persona verifies identity. One way is through something called KYC, or "know your customer." This is a process of verifying that a person is who they say they are, usually by looking at government-issued ID. Another way persona can verify identity is by looking at someone's online activity. If a person has a lot of social media accounts and is active on them, persona can use that data to verify that they are who they say they are.
