Aww man :( What's the word for "awesomeness"? So I could tell the mod to update it ;)
That said, I'm a bit leery about doing user management using third party libraries and I looked at the linked HN page to find the same concerns expressed. Please explain more about how you plan to address security concerns. Good luck!
P.S: "Mast" as posted by architgupta means "Cool/good". As always, have fun!
