If you are not the only PC user in the family, you have probably come across a situation when all family members could read your correspondence. Sometimes the information exchanged with you may be confidential or undesirable for others to view, in such cases, you can simply restrict access.
The program itself has a function for asking for a password when it starts, i.e. except you and those who know the password, will not be able to run the program. To test the operation of this function, you must first of all start the program by double-clicking the left mouse button on the shortcut on the desktop. You can also start the program if you click the "Start" menu, select the "All Programs" item and find the program shortcut in the list that opens.
After starting the program, try to log out of your account. Choose your username and enter your password. Before clicking the button to sign in to your account, uncheck Sign me in when Skype starts. This option will allow each user of the Skype program to log in only under their own username.
It is also recommended to remove the program from the startup list of the operating system. To do this, click the "Start" menu, select "Run". In the window that opens, enter the msconfig command and click the "OK" button.
In the new window, go to the "Startup" tab and find the line with the name of the program, uncheck the box and click the "Apply" button. In the window that opens, click the "Restart now" button, after closing all applications and saving the work results.
After rebooting the system, check the program for automatic start. If you are not sure that this method will 100% avoid reading your correspondence, enter system startup by accounts. For example, you can create several accounts: Mom, Dad, Dima, etc.
To do this, click the "Start" menu, launch the "Control Panel" and double-click the left mouse button on the "User Accounts" icon. In the window that opens, click the "Create an account" link.
For each such entry, you must set administrator access rights, but log in using a password. Thus, your account will not be able to log in and read your private messages.
