Techniques are disclosed for enabling a user to validate the authenticity of a computing system (e.g., an access management system) such as one which controls access to one or more resources. A user can determine the authenticity of an access management system before the user provides credential information to the access management system. A user can be presented at a client system with an interface to request authentication of an access management system. The access management system may provide the user at the client system with temporary access information to submit back to the access management system. The access management system may provide recent personal information to the user at the client system to verify the access management system. Upon verification of the personal information, the access management system may prompt the user for credential information to establish a session.
