Authentication resource

I've been starting to delve more into security, authorization and authentication – I'd like love any suggestions of resources on the subject for a beginner like me. I've included some resources I have found myself and am interested in some thoughts too.

– The Auth0 guides: https://auth0.com/docs/topics/guides

– OWASP Auth cheat sheet: https://www.owasp.org/index.php/Authentication_Cheat_Sheet

– B.U. on best practices: http://www.bu.edu/tech/about/security-resources/bestpractice/auth/

​

Thanks in advance,

John S.
