Logging in is a key part of a computer security. It’s the process by which an individual authenticates him/herself to a computer system, which then knows identity of the user. The oldest and most simple form of authentication is probably using credentials like name and passwords, but over the years other methods have been developed fx. finger print scanning, digital certificates, tokens generating unique numbers. These are well know for accessing company networks, but lately they have been seen to provide stronger security to protect values game profiles. Even though basic user name and password is one of the weakest ways to authenticate users it is the most common. Basically there is no way to ensure that it is in fact the right person logging in with a username and password combination.
