I don't need one. Here is my reply to another threat about passwords about a year and a half ago:
Not in the least. I have a coded system that only my son and oldest grandson know how to decipher. I also use a combination of lower and uppercase letters, numbers and if possible..symbols. Many sites now prompt users to use all of those and show if your password is strong or not.
I use a different password for every account and believe me I have many. I have two factor identification on certain Google accounts, all my financial institutions and personal medical portals.
I used to get on my husband all the time because his were too easy to guess. And I have a cousin who used "password" as her password. She's a doctor too! I sure hope she changed that.
My coded passwords are listed in a Google document.
