Importing OpenVPN credentials on firestick/ shield

I’m interested in trying the OpenVPN app on my shield and firestick. I am having trouble finding an easy way I’m important credentials. Is there a trick that I’m not aware of?

you need a vpn app on the device. The credentials are for a router.

Yeah seems like I’m going to have to go router route. Have any recommendations on a router? I’m tired of everytime finding a router I like and it not being VPN compatible lol

look at the asus brand
