you both should be able to sign out as you exit Skype (see the sign out icon in top right corner of the main screen), which should present the login screen when Skype is next started -- uninstall/re-install should not be necessary
N.B. the option to 'Exit and sign me in when Skype starts' should NOT be ticked -- otherwise you won't see the login screen when Skype is next started
Thank you. it worked, although on my tablet I had to click on the name on the left of the screen , this opened the profile box where I could sign out.
Got the same problem.
Basically you need to go settings > untick the sign in automatically > sign out >> enter your new username and password.
