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:
Of course everything is on GitHub if you want to look at it and put it up for yourself. If you don’t have any web hosted you could just put the scripts in the Public part of your Dropbox.
