Methods, mediums, and systems for establishing and using security questions

A computer-implemented method, comprising:

• receiving, by client-side logic of a client-side device, a request to reset a password to access a web site associated with a user;
• retrieving, by the client-side logic, a question from a block of a blockchain, the block having an answer associated with the question, and the block associated with the web site;
• displaying, by the client-side logic, the question on a display device;
• receiving, via an input device of the client-side device, a response to the question for the user;
• creating, by the client-side logic, a hash of the response;
• providing, by the client-side logic, the hash of the response to a server, the server coupled via network with the client-side device;
• and
• receiving, by the client-side logic, a determination that the response to the question matches the answer contained in the block of the blockchain and, in response to the determination, resetting the password.

A non-transitory computer-readable medium storing instructions that, when executed, cause one or more processors to:

• receive a request to reset a password to access a web site associated with a user;
• retrieve, via a network, a question from a blockchain, the question stored in a block of the blockchain, the block comprising an answer corresponding with the question, and the block associated with the web site;
• display, on a display, the question;
• receive, via an input device, a response to the question for the user;
• create a hash of the response;
• provide the hash of the response to a server;
• and
• receive a determination that the response to the question matches the answer contained in the blockchain and, in response to the determination, resetting the password.
