How this Remote log out works. Let us get to Know about Sessions?
In older implementation, server used to save the passwords of the users on PC in hashed form, whenever user log in to those account, password is accessed by corresponding site decoded and user automatically gets logged in.
Problem with this approach was anyone has access to those cookies where log-in details are saved and after bruit force, it may be decoded.
Concept of Session
Session is another way to communicate with computer browser. In session, instead of saving password or such data on system’s hard drive, server creates file on Server itself to store such information.
For accessing such data, server just create the cookies having random text, which tell server to access that particular file after cookies get verified. Once cookies verified, server finds the corresponding file on server’s own database and gets the login details from there.
User logged in easily using sessions, in above case, we just delete the session data and make the cookies saved on those unreachable system untrusted, so when those cookies sends data to server to retrieve username and password, server refuses to access and ask for the username and password again, making account log-out.
This layer up security on these accounts, and server get more secure. Such session can be easily deployed using script languages like PHP.
You can log out to your account from any unreachable system just make sure your password is not saved on those system, in such case you need to change the password. I hope you understood the concept of session, and if not go to last section again. And don’t forget to share this with your friend circle using social media. Have awesome time you all.
