We will be working with other government departments and agencies to expand the range of documents we can allow identity providers to validate.If your client application requires authentication and would like to obtain information about the authenticated person, then it should use the Open ID Connect protocol to get an ID token.To do this, they have to look at a range of evidence and different methods to reach the required level of confidence, so that someone can't easily pretend to be you using just one or two pieces of evidence.
“Identity Verification”, “Identity Validation” and “Identity Authentication” are often used interchangeably, but actually have subtle differences in meaning.
With OIDC, they can also give you a token called an ID token.
The ID token contains information about a user and their authentication status.
This might include providing details of official documents like a passport or driving licence.
In the past, to check whether these documents were valid, an identity provider would have had to make a phone call, or physically look at the documents or a copy of them.
