Forget your Password?

Better believe it! I understand the need for security but how much is too much? I have been trying to use the features of the iPhone 4 I purchased a few weeks ago. I set up an iTunes account a week or so ago and a redbox account, all of which require passwords along with gmail, my bank, Inspire (the state funded electronic database for information) and at this point I don't know what else. I know that I tried to access my redbox account and then my itunes account and couldn't remember any of the passwords. I'm sure I wrote them down on a slip of paper somewhere but where? I managed to reset one password but it's real inconvenient to be a part-time user and when you really want to access a site where you have an account not be able to remember the password for that site. How secure is having your computer remember all that information. Convenient for sure, hardly secure if the laptop falls into the wrong hands. I'm sorry but isn't there a better way to remember passwords? I can't help it if I want my access and security too. I guess I should not complain that my accounts are secure even against me. I'm thinking of the money I'll save. Maybe there is a silver lining.
