# Reusable KYC
This option is available to any client who uses WebSDK.
The process looks pretty simple:
- We check whether a user already passed verification with the same email and got approved for some client.
- We ask a user whether they want to confirm that.
- If they agree, they pass a liveness check, and we compare their face with the ID documents.
- If all is okay, we just copy their documents to your applicant.
If you want to use this option, get in touch with the Sum&Substance team.
