Sign Into Multiple Skype Accounts

Unlike some messaging programs, Skype doesn’t allow you to easily log into multiple accounts. Try to launch the Skype shortcut once you’ve already opened Skype and it will just bring your already-open Skype window to the front. But you may have multiple Skype accounts — perhaps you have one for work and one for personal use.
Rather than open Skype as another Windows user account, Skype has a hidden option you can use to open a new Skype instance.
To do this, press Windows Key + R to open the Run dialog. In the Run dialog, enter the following command if you’re using a
32-bit version of Windows:

“C:\Program Files\Skype\Phone\Skype.exe” /secondary

On 64-bit versions of Windows, enter the following command instead:

“C:\Program Files (x86)\Skype\Phone\Skype.exe” /secondary

Skype will open a second Skype window, which you can log into as another Skype account. If you wanted to use this frequently, you could create a new Windows shortcut that opened Skype with the /secondary switch.
