My phone kids me in to Skype.
My pc Skype is locked and I cannot get in because it was trying to force my to use a Microsoft login not my personal login that I have had since before Microsoft bought Skype.
The over rigorous ms account security rejects all my answers and days I am not me so it will not send me a new password.
And so I cannot get in at all, ever again from my pc.
Yet my phone works...... But I don't know what password it uses.
Many people forget their password.
Seeing a fragment of it can help them get in again.
