Earlier today I put together a simple password generator contained in one HTML document. No dependencies or resources needed.
It uses the
window.crypto number generator and a list of characters selected by the user (there are options on what characters you can select).
You can view and use the password generator at maxpelic.com/examples/password_security.html.
Let me know if you have any feedback, I'd love to hear what you think! You can email me your thoughts at email@example.com
