gnome-keyring 3.28.0.2-1ubuntu1.18.04.1 (s390x binary) in ubuntu bionic

 gnome-keyring is a daemon in the session, similar to ssh-agent,
 and other applications can use it to store passwords and other
 sensitive information.
 .
 The program can manage several keyrings, each with its own master
 password, and there is also a session keyring which is never stored to
 disk, but forgotten when the session ends.
