Hi. My name is***** you for your question and the opportunity to assist.
If you don't recall your Skype ID from years ago it will not be possible to reset your password.
Is the email address you use now a Microsoft based address such as @outlook.com, @hotmail.com, @live.com
The easiest way at this point is to set up a free Microsoft account which you would then use
to sign in to Skype. Go here: https://account.live.com
Click Create Account
You can create a new account using a phone number if you wish.
