I have two Skype accounts (one for work and another for family) and I love to connect to both of them whenever I am working behind the computer. However, the restriction of the Skype client, regardless of the OS that you are using, only allows you to login to one account at a time. If you are keen to run multiple Skype accounts on your desktop, here is the workaround.
Assuming that you already have a Skype session session running:
In Linux, press “Alt + F2″ to open a launcher.
This will launch a second instance of the Skype client where you can login to another Skype account.
In Windows, press “Windows key + R” to launch the Run dialog. Type:
"C:\Program Files\Skype\Phone\Skype.exe" /secondary
If you are running the 64-bit version of Skype, use this command instead:
"C:\Program Files (x86)\Skype\Phone\Skype.exe" /secondary
In Mac, there is no simple workaround to launch multiple instances of Skype client. The easiest way is to use the app – Multi Skype Launcher to open a second instance of Skype.
Download the Multi Skype Launcher app, extract it and click on it. It will prompt you to enter your password. Once that is done, you will see a second Skype client show up in your Mac. You can then login to the secondary account.
For both Windows and Linux, it is best that you create a desktop shortcut with the command so you can launch it easily. For Mac, you just have to place the “Multi Skype Launcher” in a handy position. Enjoy!
