This is probably the worst thing about the Internet, remembering passwords.
Until about a year ago I had the same password for almost every service, sometimes I spiced it up by adding a character in the start representing the service (F for facebook, G for Gmail and so on).
A colleague had a different approach, he used simple “passwords” which he then computed SHA-1 on. He had developed a simple java script that performed the SHA-1 conversion.
I have changed his original script a bit to be able to generate different length passwords (11, 21 and 26 characters).
You can try it out yourself, just add the following url as a bookmark (works in all browsers, I think):
To use it, put a “-” in the password box and press the link, this will give you a glass pane with a password box, just write your simple password (Facebook1234 for example) and choose the length, the script will enter the password in the field where you put the “-“.
If you choose Facebook1234 as your simple password the 21 character SHA-1 will be fc1a17377c7ed19872037.
The convert.js script is YUI-compressed, the original one is convert.js.original.
There is also a form based version if you just want the password in cleartext:
