Is it a standalone program, or an Emacs package? In the latter case I
recommend to try auth-sources.el. It is the default "password manager"
in Emacs. The Secret Service API is integrated as one backend, although
there's room for improvement.

That's possible, yes. But I doubt it will happen in reality. At least in
Emacs we could check, that a label doesn't look like an object path, and
suppress such items for being considered.

secrets.el registers for several signals already, like
"org.freedesktop.DBus.NameOwnerChanged",
"org.freedesktop.Secret.Service.CollectionCreated" and
"org.freedesktop.Secret.Service.CollectionDeleted".
We could also register for the signals
"org.freedesktop.Secret.Collection.ItemCreated",
"org.freedesktop.Secret.Collection.ItemDeleted" and
"org.freedesktop.Secret.Collection.ItemChanged" in order to be notified
about such changes.
I don't know whether I have sufficient time to work on secrets.el next
weeks. Would you be interested in providing respective patches for secrets.el?
Best regards, Michael.
