I don't think they do. They get email, 3d point face cloud, IP that's it. Hard to rebuild identity from that to forge it for other means. Simpler with other approaches. Still feeling safe :)

it's easy to secure this by having the company NOT hold any valuable data:
Use the data (like face) on the phone to generate a reproducible random hash, use that hash as a seed to generate private key.
No need to store anything on a server ever.

Hope they'll put in on chain :)
what you are talking is scifi, impossible to generate private key from facial data. It is also impossible to verify if one is the original user without storing any personal data.
Why is it impossible to generate private keys from facial data?
I understand why you ask the question. A lot people have same doubt that Volt generate private key by users' face and it can be used to unlock a bitcoin wallet. Those who think so have no idea about how encryption works in bitcoin.
