How to not ever lose your passwords:
salt term + individual term
letter replacement + capitalization
Salt Term: Is called a salt term coz you put salt on everything. This is one word that you include in all of your passwords. Since you're a nerd, your salt term will be "nerd" for this example.
Individual Term: Something individual to the subject of the login. For instance, if it's a website login to a forum about dogs, your individual term could be "dogs" ..or.. if your website is about skiing, your individual term could be "ski" ..or.. if you want to be more specific, if your logic was for project 1999, your individual term could be "project" or even "project1999". Whatever you end up deciding as an individual term, stick to that scheme, so "face" and "project" or "book" and "1999" rather than "face" and "1999" - this is mainly a way to ensure memory.
Letter Replacement: Zh0u1d b3 Z31f 3xpl4nit0ry. My suggestion is to pick one or two letters in your salt term, and one or two very common vowels, and stick to that. It doesn't have to be 4 for a, and 1 for l. Stick to a few alterations, and you will remember it.
Capitalization: pick a letter of your salt term, and ALWAYS capitalize it and any like it in the individual term. I've chosen d in the below examples:
example passwords built on this idea:
n3rDD0gs
n3rDsk1
n3rDpr0j3ct
As you can see, each password is unique to the website without being easy to guess outside of the context of knowing your salt term. Each password also contains a seemingly random combination of alphanumerics including case sensitivity where those passwords are differentiated. Each password is also extremely easy to discern for any individual website without having to memorize anything but your system.
The other beauty of this system is that at any time you can change all of your passwords easily by just changing the salt term.
There, now you never have to whine on rnf ever ever again about this stupid ass shit. L2computer, noob.
