On most systems, gnome-keyring would be handling the keys for your browser and other applications, but they have this set up with GNU. I'm not sure where that is happening, but it is. Most users never know that this is going on in the background because your keyring password is being passed to the daemon silently. No intervention needed. Nevertheless, some users like to roll their own and opt for ssh-agent or gpg-agent instead of gnome-keyring. After trying to fix the code for start-cosmic, I realized the gnome-keyring wasn't involved at all and that it must be GNU. What a strange and esoteric find...Spent all morning on it.
