Abstract: The present disclosure involves systems, software, and computer implemented methods for user-controlled access control for user information. One example method includes sending an authentication request to authenticate as a requesting entity to a first decentralized resource directory of a providing entity. An authentication challenge is received, via the connection, from the providing entity, and in response to the authentication request, to store an authentication challenge value for an authentication challenge key in a second decentralized resource directory of the requesting entity. The authentication challenge value for the authentication challenge key is stored in the second decentralized resource directory. An authentication challenge response is sent to the providing entity requesting the providing entity to verify the authentication challenge.

Abstract: The present disclosure involves systems, software, and computer implemented methods for enhanced login processes. A first login page of a website is received that includes a field that enables a user to enter a handle for a decentralized resource directory. A handle for the decentralized resource directory is received in the field and provided to a webserver. A second login page is received that includes a challenge code for the handle. A challenge value is generated based on the challenge code. A location in the decentralized resource directory is determined, based on the challenge value. A request is sent to a protocol server that manages the personalized resource directory to store the challenge value in the decentralized resource directory at the location as a login challenge response for logging into the website. A login result page is received that indicates a result of the webserver processing the login challenge response.
