make_password shouldn't accept values other than bytes or string as an argument — at Initial Version

Description

Currently make_password function accepts almost every Python object as an argument. This is a strange behaviour and it results directly from force_bytes casting objects to str. We should throw the TypeError when passing anything but bytes or str to make_password.

Reasons:

  • users unaware of this strange behaviour can accidentally create weak passwords (potential security issue)
  • other libraries throw the TypeError in the same cases (eg. Werkzeug, passlib)
  • it's inconsistent with the documentation that says:

    It takes one mandatory argument: the password in plain-text.

  • it's inconsistent with validate_password behaviour (passing anything but bytes or str to validate_password raises the TypeError with default settings.AUTH_PASSWORD_VALIDATORS).
