Hello,
You can do this either directly from Copernicus Open Access Hub (https://scihub.copernicus.eu/dhus/#/home):
either from SNAP, Product Library (using the account created on https://scihub.copernicus.eu/dhus/#/home)
First define your username here (for SciHub):
And then you can use it to search products using Product Library:
