Better SSH key handling? (lemmy.remotelab.uk)

Hey folks, I have multiple VMs and personal machines across multiple cloud providers and I'm beginning to get frustrated with ssh key management. Each personal machine has it's own key so if I lose it or it's compromised I can just remove the key from the vms but it's starting to get tedious making sure everything is up to date and any new keys are added.

Are there any solutions out there that would help?

Get a usb dongle that contains the key and handles the crypto without exposing the key to the host (eg yubikey is popular). This way your secret travels with you and you have one key for all. Be sure to have a script ready for revoking the key on all machines in case you loose it :)
