I use a simple 'cipher' that makes new passwords easy to remember and remains relatively secure without the need of a book/service.

I have a file of the first word that comes to mind for every letter in the alphabet. Then my password is created based on some features of the site.

I.e. eBay has 4 letters so I could choose: 'Elephant_4_Yankee'

The delimiter is up to you and you could just as easily choose every second letter or whatever.

Yes, it does mean my Netflix password is a bitch to put in but I know it off by heart.

Second this. Domain should generate chiper for a password. You get unique password for every website and you dont have to remember it

If I’m understanding your suggestion correctly, it contains an attack vector where Provider B can obtain your password for Provider A by getting you to sign up for a new account and presenting the same “cipher” as Provider A.

Only problem is this would allow some pretty simple dictionary attacks if you use the method described.
