About a year ago I wrote a blog post on a business called 1password.
I am amazed at how many times I go to log in to a website and have forgotten my username or password. Now that I have developed and manage several websites and databases with students and customers, I notice how frequently people request their password or have trouble logging in. The service 1Password has been a life saver on more than one occasion!
If you want a very secure place to easily store and organize all your passwords (and more, like your credit card numbers) I highly recommend you read this blog post and check out 1Password. It's so worth it!
