Now if they forgot their password, I want to email them the password so they can login and change it. How do I reverse the bcrypt encryption to get the original password back?

推荐答案

Bcrypt是单向哈希.您无法解密.您可以做的就是向他们发送一个重置链接，单击该链接将允许他们设置新密码.

Bcrypt is a one-way hash. You cannot decrypt it. What you can do is send them a reset link which, when clicked, will allow them to set a new password.
