Today we've published a guide on GOV.UK that explains in more detail what checks identity providers must perform to meet the published standards.
When you use GOV.UK Verify to access a government service, you will be asked to choose a certified company. The certified company (also known as an 'identity provider') will verify your identity to a defined level of assurance to meet published government standards. They will ask you to give them some information and carry out some checks to allow them to verify that it's really you.
Any information stored by the identity provider has to be stored securely and handled in accordance with data protection law. They are not allowed to use data you provide for any other purpose without your informed consent.
We hope this guide will help people understand how GOV.UK Verify works. We'll welcome any comments about how we can improve it to make it clearer and more informative.
