  The phase synchronization of a single qubit in a dissipative bath in the
absence of driving field is demonstrated. Using the Husimi $Q$-function we show
that the phase preference is present in the long time limit only during
non-Markovian evolution with a finite detuning. This happens due to the
information backflow signifying that non-Markovianity is a resource for quantum
synchronization. To quantify synchronization we use the shifted phase
distribution as well as its maximal value. From the maximal value of the
shifted phase distribution we observe the signatures of quantum synchronization
{\it viz} the Arnold tongue. In our case the region ofsynchronization is
outside the tongue region and the region inside the tongue is the
desynchronized region. This is in contrast to the results in the literature,
where the synchronization is within the tongue region.
