Do we really need to remember all the password?

I'm just wondering if we really need to remember or note down all the passwords we use for sheer amount of applications nowadays. Why can't a user just click on forgot password every time he wants to login? This solution does exist for mobile apps where user gets a OTP whenever he wants to login without getting asked for a password.

A system generated password is more secure than random user generated. Although, there are some disadvantages like a) Few of the applications doesn't generate random keys but force user to reset password. b) Resetting a password is complicated and time consuming in bank sites as it takes good amount of time to reflect or you may have to visit the bank in person (esp. in India)

I do follow this practice quite often but I'd like to know if anybody else follow the same pattern. Or is there any research down on this topic so far. Any thoughts?

EDIT 1: Adding more information

  1. I want to know if anybody has done any user testing or any case study available?

  2. I'm looking for communities's thoughts. Would they try forgot password link rather than storing the password after reading this question.

  3. How many people use this option[again it is open ended]

EDIT 2: Few of the commenters suggesting password manager but I feel they are costly for individuals and security issues would always be there.
