Embodiments use credential authentication and user information verification to allow range-limited access of security information to a user. Certain information sharing protocols may require an unambiguous grant to share the user's security information with the requesting entity. In some scenarios, such an explicit grant may be impractical, such as when a user cannot provide such an explicit grant. Embodiments of a security information manager can allow a reviewed entity to range and time limited access to security information of a user in such scenarios, such as when the reviewed entity provides an assertion that the user cannot provide an explicit grant. For example, in one or more scenarios with an emergency situation, the security information manager can allow a reviewed entity to access a limited range of user information corresponding to a relationship of the reviewed entity to a user, a role in a workflow, or other suitable characteristics of the reviewed entity.
