Is there now a straightforward way (on both platforms) to use KeePassXC in the role of login keyring/keychain? Last time I looked, admittedly not recently, the answer was “we think you shouldn't want this”.
I don't know, I do everything manually. I remember most of my passwords, but when I forget one I open KeePassXC and copy-paste the pwd into the login. And once every month or so, I'll manually ssh the databases around in a round-robin manner and merge them on every machine. Mainly b/c my pwd database is one thing I don't really want to trust to the cloud, and the manual effort of not doing that isn't too onerous.
