Skype password lost -> reset email -> new password given -> login failed on skype client -> login via website -> invalid password -> reset password -> first enter code by email -> done -> assign new password -> login via password -> someone else is using your account, you have to change the password -> first ensure you are you by enter a code -> code entered -> change password -> password changed -> finally login works
Way to go Microsoft!

so I just changed my password 3 times in the last 5 minutes to get access to skype... for a call we finally made via whatsapp... now I will remove skype again until next year, when I have to make that famous "once a year" call with skype
