We compare the photo from your document with the photo you took to set up your Yoti. Then we use document verification to confirm that the passport belongs to you.
We then delete the passport scan/photo up to seven days after submission. Meaning only you hold a copy of your document.
For driving licences and national identity cards we also use your name, address and date of birth to check your identity against an approved identity provider. We ask for permission to do this when you add a document.
