# Authentication When issuing a credential, issuers must have adequate mechanisms to assure and authenticate that the identity of the individual claiming the credential matches the subject of a claims. Velocity Network includes authentication methods that enable the issuer to obtain rigorous proof required to confirm that the individual is genuinely who they claim to be before issuing credentials to this individual. Issuers identify individuals on the Velocity ecosystem either by using preauth codes they send to a person's email address that can be corroborated by a pin, or by having the individual share ID credentials and prove that they are the owners of those credentials by using a cryptographic proof of control protocol. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://velocity-network.gitbook.io/velocity-network/implementing-proof-of-qualifications-at-scale/authentication.md?ask= ``` The question should be specific, self-contained, and written in natural language.
