Never write down your password, and never store it in your browser. If you have many user names and passwords (as we all do), it's impossible to remember them all. Some form of storage is needed. Utilize a password manager application. A password manager automates the random generation of all passwords for each of your accounts, allowing you to remember only one strong passphrase (see prior blog posting.) Password managers have strong encryption and can pseudo-randomly generate strong passwords for each unique account you log in to.
Here is a non-extensive list of password managers, as of September 10, 2015, from Wikipedia. https://en.wikipedia.org/wiki/List_of_password_managers
