There are some services that I expose to the internet (using Apache reverse proxy) that really should be accessed by only a small set of devices. Requiring client certificates seems like a great way to reduce the attack surface and prevent brute force attacks (since the attacker doesn't even get a chance to attempt a login).

I wonder about the difficulty on the client side as well as other practical implications. The clients are smartphones of various makes.

I am using mTLS implemented by nginx to access my services like Home Assistant, Paperless, Tandoor, Immich and so on. Clients are Windows, Linux and Android based so no iOS experience. Adding new clients can be tricky if you need to figure out how to provide the certificate first. Once it works, it's rock solid
