ID.me

ID.me is a digital identity network that simplifies how you prove who you are online. Instead of creating new accounts and uploading documents for every service, you verify your identity once with ID.me and use those credentials across a vast network of partners. This approach reduces friction while maintaining high security standards for sensitive transactions with government agencies and healthcare providers.

You can use the platform to access state benefits, federal services, and exclusive discounts based on your professional status, such as military, student, or first responder. For businesses, it provides a pre-verified pool of millions of users, helping you reduce fraud and onboarding drop-off rates. It effectively bridges the gap between high-assurance security requirements and a smooth user experience.
