I've long used yubikeys for SSH authentication and git commit signing, but recently realized that laptops all have security tokens built in these days! So I spent some time setting it up so I just use my macbook's secure element to do all that. Here's a post I wrote about it.

Credit to @arianvp@functional.cafe for the instructions on how to do this! Still waiting for someone to tell me that posting all my private keys was a bad idea lol

@ahelwer@discuss.systems I just ran into a very sad thing here, which is that if you have one of these public keys in your GitHub account, and you have automation somewhere that uses those keys to create EC2 instances and keypairs... you're gonna have a bad time. :(
