        if (
          reason === PasswordResponses.NEED_PASSWORD &&
          !passwordNeededCapability.settled
        ) {
          passwordNeededCapability.resolve();
          updatePassword("qwerty"); 
          return;
        }

        expect(false).toEqual(true);
      };
      const data = await Promise.all([
        passwordNeededCapability.promise,
        passwordIncorrectCapability.promise,
