Per,

I would love to hear more on this. The OWASP foundation has a living 
document on this topic and I would be grateful for any help to give 
better advice.

https://www.owasp.org/index.php/Forgot_Password_Cheat_Sheet

While we are on the topic, I'd also love any review and edit suggestions 
to...

https://www.owasp.org/index.php/Password_Storage_Cheat_Sheet

These are all open source documents meant to help inform developers to 
do the right thing. I appreciate any help from you.

Aloha,
Jim Manico
