Firebase or Google OAuth for security and user data

Hi there,

I am looking to use Webflow to develop a web app for my company.

I need to use a google login that works for anyone with a company domain email.

I wanted to know the possibilities of integrating one of these systems and what would be the best.

The login just needs to be a secure way that only users with the company domain can access the site, because its supposed to be a tool to help employees and the information needs to be private.

Thank you guys for your help.
