How add a new user and password

I have Pynq running on ZCU208 with the default password (I am not asked for a username). Since two development teams will share this kit, I would like to create two accounts that would be separated with their own files. Is that possible? If so, how? Thank you very much. P.S. I’ve looked at the guide for adding a new user in Jupyter, but within Pynq, I don’t see such an option in the GUI.
