Entering a Excel File with a login on a domain

[tico_ocit]

Hi there,
hopefully you can help me on this.

I working on a excel file that basically categorise your expenses by the categories that you create, and you can see the evolution of them.

This idea came out when I got fired in the beggining of Covid-19 pandemic. So I'm not pretend to sell, but to ask for a contribution. But I would like to create same kind of login. I know that it is possible to workaround on that, even protecting with a password the code, but I can live with that, I can't stop people for sharing.

What I'm wondering is that when you open the excel file, run application.visible=false and show a login userform, that you enter the login parameters it goes to some domain on internet and see if it is a authorized login. Can I do that? If so how?

I'm thinking ok, but people, can share the login. Yes it's true, but can I limit to a specific environ("username"), or set that one when you open the excel file for the first time?

This is being a big adventure while searching for a job, and I'm learning a lot.

Thank you in advance for any help!
