Different User for different thread

[alisterubuntu]

Hi,
Could you please help me with a small question on Xdist

I am testing a application using selenium pytest and xdist. I want to run the test cases in parallel. But how do i pass different user credential to each thread in Xdist? Suppose there are 2 xdist thread execution, then 1st thread has to use USER A and second thread has to Use USER B credentials from CLI or Json etc.

Thank you,
