Hey thanks pilingual. We recently released this to the general public. We'll roll out a simple video and screen shots soon. Here is the two-step enrollment process for users that need to verify their identity:

1. User gets their Changefly ID through the Changefly app (free)

2. User verifies their identity anonymously (https://www.changefly.com/account/verify)
