MacOS SSH config for secure keys (secure enclave + touchid, yubikey)

	# to use the "tagged" config on the commandline:
	# ssh -P <tagname> example.com
	# to reuse the config in a Host block, use as stanza within the Host block
	# Tag <tagname>
	# see also https://man7.org/linux/man-pages/man5/ssh_config.5.html


	# MacOS secure enclave + touchid
	# see also https://gist.github.com/arianvp/5f59f1783e3eaf1a2d4cd8e952bb4acf
	# requires downloading key first, disable password (it needs touchid anyways)
