There plenty of tools working with keyrings: ssh-agent, gpg-agent, gnome-keyring, kwallet, wrappers like keychain, keyctl talking to GNU/Linux kernel. There are various recommendation on how/when to start it tailored for different environments.
This make it rather confusing. I'm using modern GNU/Linux distro with systemd and I start my user session with systemd --user as well. I expect this setup to last decades so I wonder what's the best way to get keyring into picture?
The main use-case is to store passwords from chromium/firefox in one consolidated place.
Shall I start keychain from my user shell autostart script (I use fish for interactive and dash as login shells if that matters)? Right now "gnome-keyring-daemon --daemonize --login" is spawned via PAM. Shall I start "gnome-keyring --start" from user systemd unit? Is there some dbus service which would start some keyring daemon upon first request?
The list of questions go on but you get the idea - what is the right way to get keyring-as-a-service?
