Hello Experts, I hope you're doing good, here is my question
I want to setup a security application, where I generate a Key, I send it back to the user in question, then, he installs it in his browser let's say 'Firefox' then, when he tries to login to his account, the server looks up at the key installed in firefox through SSL then guarantees the access for the user.
The server or the website should not give the access to the user to login to his account even if he got the correct login and password unless he got that key installed in firefox.
Any idea?
Thank you
