Skype can a lot: reduce the distance between people located at different ends of the globe so that they can not only talk, but also see each other. With it, you can write free messages. But it is impossible to change the eventually installed login to Skype. Exit - change the nickname that other users will see.
So, the login is a unique name that you entered during registration. It is also used to enter the program and remains unchanged, but by performing simple settings, you can forget about it. Not really, of course, because the login is always needed in the event of a password recovery. In addition, it will be present in the top of the window next to the inscription Skype. To start when starting Skype in the welcome window, put a tick opposite the phrase "Automatic Authorization when starting Skype". Now the entrance to the account will be occurring without the introduction of registration data (that is, the login and password).And one more important refinement: all people included in contacts can assign you a completely different name that will be visible only to them. For example, just a common name that is more familiar. And all changes to the displayed Nick in this case will not help.
