Surface the login keyring, and offer to unlock it
The keyring is already unlocked at sign-in exactly as GNOME does it --
pam_gnome_keyring is in GDM's stack and the journal confirms it works
("gnome-keyring-daemon started properly and unlocked keyring"). So there
was no configuration bug to fix. What a bare Hyprland session lacks is
anywhere to see when that has stopped being true.
It stops being true rarely and expensively. gnome-keyring-daemon crashed
once on this machine -- an upstream abort in service_method_open_session,
with a core dump -- and D-Bus then activated a replacement. That
replacement never received the login password, so the keyring was locked
in the middle of a session that had unlocked it correctly at login.
Nothing announces this. What you see instead is a mail account that will
not authenticate, a git push that cannot find its key, or an integration
reporting "not configured", none of which mention keyrings. That is the
same root cause as the Home Assistant token failure earlier.
Privacy & Security now shows the state, offers an Unlock action that
raises the standard password dialog, and reports when the daemon holding
your secrets is a D-Bus replacement rather than PAM's -- because a
replacement that is currently unlocked was unlocked by hand and will not
survive a restart. The password never passes through Panama.
The contract stubs the secret service rather than touching the real one:
locking the login keyring breaks every saved password on the machine and
can only be undone by typing the password into a dialog, so it is not
something a test suite may do to a daily driver. Verified it catches a
helper that misreports locked as unlocked, and one that crashes instead
of reporting a missing service.
Worth recording: a locked keyring makes a NON-INTERACTIVE caller appear
to hang. It is not hung -- it is waiting on a dialog nobody is looking
at, which is exactly how the earlier secret-tool investigation lost an
hour.

"""The login keyring's lock state, and a way to unlock it.
|
||||
|
||||
Why this exists
|
||||
---------------
|
||||
GNOME unlocks the login keyring at sign-in through pam_gnome_keyring, and so
|
||||
does this desktop -- the PAM stack is GDM's and it works. What GNOME also has,
|
||||
and a bare Hyprland session does not, is anywhere to SEE that it failed.
|
||||
|
||||
It does fail, rarely. gnome-keyring-daemon can crash (an upstream abort in
|
||||
service_method_open_session, seen once here), and when it does, D-Bus activates
|
||||
a replacement. That replacement never received the login password, so the login
|
||||
keyring comes back LOCKED in the middle of a session that unlocked it correctly
|
||||
at login. Everything that stores a secret then starts failing in ways that do
|
||||
not mention keyrings at all: a mail client that will not authenticate, a git
|
||||
push that cannot find its key, an integration that reports "not configured".
|
||||
|
||||
So this reports the state plainly and offers the one action that fixes it.
|
||||
|
||||
Unlocking prompts
|
||||
-----------------
|
||||
`unlock` asks the Secret Service to unlock, which raises the gcr password
|
||||
dialog. That is deliberate: the password is not ours to store or handle, and it
|
||||
never passes through this script. The dialog is the same one GNOME shows.
|
||||
|
||||
Note that a locked keyring makes a NON-INTERACTIVE caller appear to hang -- it
|
||||
is not hung, it is waiting for a dialog nobody is looking at. That is worth
|
||||
knowing before debugging one for an hour.
|
||||
|
||||
Usage:
|
||||
panama-keyring status -> {"available", "locked", "collections", "daemon"}
|
||||
panama-keyring unlock -> raises the password prompt; prints the new state
