If Google has their way, the days of memorizing passwords may come to an end. I know people who are always forgetting their passwords. Possibly, you are one of them. I use a code and system for my passwords that rarely fails. It works even if I’ve not been to a website in years. The key is to make up a standard portion to all your passwords that you can apply to an element of the site you are visiting.
For example (This is not my version of the system) you can use the first two letters of your middle name, birth month and combine them with the last three letters of the website name. There are many ways you can do this and once you are accustom to the pattern, you will hardly ever forget a password.
