I have always seen those "Forgot password" links from web sites that requires some form of user login. Can I get a deeper understanding of how this works? What tools/framework do I need to use because we are thinking of implementing these kinds of "automation". I believe I need a combination of email, OTP etc.
We are currently still in manual mode, i.e by sending password letters through snail mail and I am thinking of revamping our site. thanks
