There’s a great post in Hans Anderson’s blog on secure password patterns and how you can create one. There are at least two things I like about this entry. The first one is the statement that "No password you can remember is unbreakable", this means sooner or later it is broken. The second one is that Hans points out, you should never disclose your password pattern to anyone. I agree that password patterns are awesome but they are still vulnerable to social-engineering-based attacks. By the way, why not share your password pattern ideas in the comments?
