Hash the user's primary key, email (if available), and some user state
that's sure to change after a password reset to produce a token that is
invalidated when it's used:
1. The password field will change upon a password reset (even if the
   same password is chosen, due to password salting).
2. The last_login field will usually be updated very shortly after
   a password reset.
Failing those things, settings.PASSWORD_RESET_TIMEOUT eventually
invalidates the token.

Running this data through salted_hmac() prevents password cracking
attempts using the reset token, provided the secret isn't compromised.
