Is there a possibility to restrict access to the information and data on a website if the user is not using a specific web browser? Want to develop a web browser that can view only one website. I am developing an NFT marketplace and for security reasons, I want to fuse a website and a web browser in one. Didn't see anyone do this before. Is it possible to restrict it with javascript and/or jquery?
You can read the UserAgent header, or navigator.userAgent in JavaScript. This is only for user convenience though, not security, as a user can change their UserAgent to anything they want.
