Ryan's guide to determining whether your password is secure:

1) Did you pick it yourself? If yes, it is not secure.

2) Is it unique? If no, it is not secure.

3) Is it part of a "password system"? If yes, it is not secure.

4) Is created using a deterministic password generator? If yes, it's part of a "password system" and therefore not secure.

5) Did your password manager randomly generate it for you? If yes, it's probably fine.

6) Did you generate it with dice? If yes, it's probably fine.

7) Did you create your password in some other way? It's probably fucked.
