Pssword control
What can Y do to replace all my passwords into only one : - having something from the alphabet and some current number (eg ABC321) - which is only valid for a chosen period as chosen by a user (eg until March 2021) - that informs me by a message like "Be attentfull : your password is soon retired. Renew it soon" - that can be used on an old Pc with Microsoft Vista.... - ...and on a relative new laptop with Windows10 - also on a HuaWay if possible - when I am dying, the password should further exists until the password time is gone.
In this case I never have to make and hide a list where I can forget the hidden place or finding old (wrong) passwords or never forget what the other passwords were.
