only one password for all ?
it's easy.
I have a master password for my main Gmail and main FB account
then I have lots of suffix and prefixes. when I want to create password i create a new suffix or prefixes and add that to the master password.
EX: master pass: EXtr0 strenth
Sufix: #66984*
Password: EXtr0 strenth#66984*
to tell you the truth I have a lot of Facebook accounts (more than 50). so I only remember the suffixes and it is the account's email name phase
so if I know the mail I know the password. but I add extra things in between the master password and suffix or prefixes to protect it
