It's monumentally stupid to think auth is easy. Yes there are standard cookbooks and checklists out there. The hubris to think that auth fails due to a crypto scheme choice is why average programmers consistently fail at it.
The yearly report of leaks in Fortune 500 companies should be proof enough of this.
EDIT: To elaborate. Crypto scheme is only one tiny facet of a successful authentication solution. Where do you store the hash? What language and stack are you using? What is the maturity of libraries available to you? What protocols? And many more seemingly tiny decisions. All it takes is a lazy developer that imports an insecure transient dependency or snoozes on a CVE.
