Here's my anecdata: I didn't know much about ssh keys when creating, so I followed directions online. The directions I followed created my key with no password. Soon my Mac encrypted the ssh key by itself, without my intervention (!), to use my Mac logon password. The encryption format was the old ssh format the article complains about, even though my openssh supported the new one. The password I use to sign into my computer is not grabbed from a password manager.
