## Where their work shows up

Revision 4 had to answer questions revision 3 did not face: whether a synced passkey counts as a phishing-resistant authenticator at high assurance, how digital wallets and [verifiable credentials](https://startwithidentity.com/standards/verifiable-credentials/) fit into proofing, and how to write proofing requirements that do not exclude people without conventional documentation. Those answers shape federal procurement and, through it, a large part of the identity verification market. See [NIST 800-63](https://startwithidentity.com/glossary/nist-800-63/), [passkeys](https://startwithidentity.com/glossary/passkey/), and [identity verification vendors](https://startwithidentity.com/vendors/identity-verification/).
