How to scale up selenium?

Hi guys! Currently, Im working on ideas on assignment reminder, which reminds me the assignments which are gonna out of date. I wrote a selenium and bs4 to do that job, it works well to me but if I want scale up to multiple users such as usr1 type in his account and the script will scrape data with that account, usr2 also type in his account and so forth. The question is how do I achieve that? Thanks
