Do you have trouble remembering passwords because there are so many? Maybe you use the same password for everything; that's risky!
Consider using LastPass. With LastPass you just have to remember one password, then LastPass remembers the rest for you. You can add the LastPass extension to your browser, sign in, then LastPass will fill in your Usernames and Passwords. For $1 per month (charged at $12 per year), you can use LastPass on your mobile devices, too.
Beef up your security and put your mind at ease by using LastPass to keep your passwords.
P.S. LastPass has been around a long time and has proven to be secure. Here's an independent article about security: Is LastPass Secure?
