Steps to enable automatic login without asking for the password in GNOME, KDE, and Ubuntu MATE.
When we use Linux distros, in this specific case Ubuntu 16.04, it is common that the system requires us to access credentials.
This is configured from the moment of the installation and is applied as a security measure to prevent the unauthorized access of users to the system, putting at risk the integrity and security of the information.
By default, if we want during the installation process this option can be set but not always consider, and if our team is safe and only we will access it is practical to enable the login form automatically and thus save time in accessing Ubuntu 16 or 17.
