A system is disclosed that enables network-based systems to confirm the identity of users and/or the authenticity of their credentials during their registration process by providing a database of verified users and various means for requesting and verifying user-provided information using the database. For example, the system may verify credentials and/or other aspects of the user and store such information in a database. The system may also generate badges that can be displayed on various content sites and that link to a summary of the user's verified information. The summaries may be customized for each content site at which the user has registered.
