Browser Support Information

I am working on a web portal design and it used by enterprise admins. I am not sure which device (Laptop/PC) or which browser they are going to login and use the portal, so wanted to show the "Browser support” info.

Thought of two options,

Option 1: Once the admin open the portal - on login page itself, displaying the browser support info in a popup upfront. Admin read the info - close the popup - go ahead and log in on same browser or uses another browser (which is supported) to login. Once logged in to the portal, the same information will be added in footer throughout the portal.

Option 2: No popup displayed upfront, browser support info will be added in the footer - in login page & in all other portal pages.

Suggestions to improve the experience to show the browser support info...
