@Starou Can I suggest we also update the _make_token_with_timestamp with

        secret = settings.SECRET_KEY + str(user.id) + user.password + str(timestamp)

        # No longer using last login time
        from hashlib import sha1
        hash = sha1(secret.encode('utf-8')).hexdigest()[::2]

        return "%s-%s" % (ts_b36, hash)

I got NameError: name 'unicode' is not defined when hitting .../token/new.json

@tenkunkyab: can you be more specific about the error and how to reproduce it please?
