Earlier today I was setting up a brand new server for a migration and just as I was typing scp .ssh/authorized_keys2 my brain went and asked a question..
What is the difference between authorized_keys and authorized_keys2?
I’ve been working with Linux for well over a decade and some of my practices stem from things I learned in the ’90s that still work, putting all my public keys in ~/.ssh/authorized_keys2 is one of those things.
