About the "Forgotten Password" put in a word.

There is always the problem of how to remind the user of a password that he has forgotten. There are lots of options, just changing the password by the robot before saving the security question. So I would like to ask people what is your favorite method?





I absolutely do not like the options with a control question, so I will list the options for reminders without them:



1 - The user enters his e-mail and a letter with a new password is sent to him

2 - The user enters his e-mail and a letter is sent to him with a unique URL where he can simply enter a new password.

3 - The user enters his e-mail and a letter is sent to him with a unique URL by clicking on which a new password will be generated and he will receive an email with a new password. (that is, a kind of upgrade of the first option)

4 - The user enters his e-mail and a letter is sent to him with a new password, but with the text that it is activated if he follows the link.

That vobschem something that occurred to me. If you have your thoughts, I will be very happy to hear them out.
