Hi @janaidfarooq34, welcome to the community and thanks for posting this here 
It looks as if you are using airtable to create a user login system. I would advise against this as there is potential for the information to be stolen and you have to code the entire thing. Plus, you can see your user’s passwords, which is not cool.
Instead, I would recommend following the instructions here to set up a free RealtimeDB login system managed by Google. If you run into issues there, please post then!
