fix(auth): pin the linux keyring backend so logins survive switching desktops - #302
On Linux, a login now survives switching between desktop environments or window managers (e.g. KDE ↔ GNOME ↔ Hyprland/sway), as long as every session uses the same Secret Service provider (see below). Before this, the app signed you out every time you switched.
Why
Both auth/session.json and auth/youtube-session.json are encrypted with safeStorage. On Linux, Chromium picks the keyring backend from XDG_CURRENT_DESKTOP: kwallet5/6 on KDE, gnome-libsecret on GNOME/XFCE/Cinnamon, and basic_text (a hardcoded key) on everything else. Each backend uses a different key, so a session written under one desktop fails to decrypt under another. AuthSessionStore.read() then logs stored session is unreadable and returns null, and the next login re-encrypts the file with the new key. That breaks it for the first desktop too.
How
electron/secret-service.ts asks the session bus (dbus-send, ListNames + ListActivatableNames, 1 s timeout) whether org.freedesktop.secrets is running or can be activated.
electron/libsecret.ts looks for libsecret-1.so.0 in LD_LIBRARY_PATH and the system library dirs (multiarch, lib64, lib). The AppImage doesn't ship libsecret, and an explicit gnome-libsecret that can't load leaves safeStorage without encryption instead of falling back to KWallet.
electron/password-store.ts pins --password-store=gnome-libsecret on Linux only when libsecret is installed, a Secret Service is there, and the user didn't pass their own --password-store. Otherwise Chromium's default backend stays, so nobody gets downgraded to basic_text by this change (e.g. KDE with KWallet's Secret Service API turned off keeps the KWallet backend).
electron/main.ts appends the switch before app.ready, next to the other command-line switches. The same os_crypt key also encrypts Chromium's cookie store, so cookie-based logins are covered too.
Unit tests for both modules.
Requirement: one Secret Service provider across sessions
The pin means the app always fetches its key through the Secret Service API. The key lives in whichever program provides that API in the current session (gnome-keyring, KWallet 5.97+, KeePassXC…). If none is stored there yet, the app creates a new one. So:
Works: every session uses the same provider. For example, gnome-keyring on GNOME and on Hyprland, or KWallet on KDE and on sway.
Still signs out: sessions use different providers, e.g. KWallet on KDE but gnome-keyring on GNOME. Those are two separate stores with two separate keys, and the app can't reconcile them. The fix on the user's side is to run the same provider everywhere.
Unchanged: a session with no Secret Service at all keeps Chromium's default, as it does today.
Other things worth noting for review:
Users currently on the KWallet backend (KDE) are signed out once after updating, because their file was encrypted with the KWallet key. After that it stays put.
The checks run once at startup and only on Linux. If libsecret isn't found (e.g. a non-FHS layout like NixOS), dbus-send is missing, or the bus doesn't answer, nothing is pinned and behavior is the same as today.

Summary by CodeRabbit
Improvements
On Linux, the app now selects GNOME’s password store by default when a compatible secret service is available and no password-store option has been specified.
If you provide a password-store option, the app preserves your choice and does not replace it.
On Linux systems without a compatible secret service, the app does not apply this default.
Password-store behavior on Windows and macOS remains unchanged.
…desktops
Chromium chooses the safeStorage backend from XDG_CURRENT_DESKTOP (kwallet on
KDE, libsecret on GNOME, a hardcoded key on other window managers), so a
session encrypted under one desktop could not be decrypted under another and
the app signed out on every switch. Pin gnome-libsecret on linux, which every
Secret Service provider serves, unless the user passes --password-store.

Walkthrough
The change adds checks for libsecret and Secret Service availability. On Linux, when the user has not supplied a password-store switch and both checks succeed, Electron main appends gnome-libsecret as the password-store option.

Merge Risk: Minimal · up to 14dd8
No confirmed new issue blocks merging. Compatibility with existing KDE sessions remains unverified and warrants a running-app check.
Security architecture risk: Low · up to 14dd8
The change is limited to Linux and preserves explicit backend choices. No introduced vulnerability was established, but protection and compatibility when a keyring fails to initialize or the application is rolled back remain unverified.
Retained concerns
No architecture-level concerns identified.
Security review details
Security Blast Radius
inferred — The demonstrated credential-state scope is the application's user-data profile, including application and YouTube access and refresh tokens. Automatic backend selection is restricted to Linux launches without an explicit password-store option.
Security Findings and Attack Paths
observed — The changed startup caller supplies local process configuration rather than renderer or request data. LD_LIBRARY_PATH influences the file-presence probe, while the D-Bus helper executes a fixed command with separate arguments and fixed method names. This establishes local environmental influence, not a remote injection path.
Trust Boundaries and Controls
observed — Explicit backend choices and non-Linux platforms bypass automatic selection. The availability checks establish file presence and service advertisement, but do not verify library loadability, provider initialization, or the resulting encryption capability.
Resilience and Maintainability Implications
observed — A session decryption failure returns null without deleting the stored file, and that result is cached in the store instance. A later valid session assignment writes using the current cipher. The application has no backend-specific recovery branch in these paths; exact runtime migration and fallback behavior remain unverified.
Hardening Proposals
proposed — Validate the shipped Electron runtime with existing encrypted profiles across backend changes, an advertised provider that fails initialization, repeated launches, and rollback. Check actual encryption availability and old-ciphertext readability rather than treating probe success as proof of either guarantee.

the Secret Service API. Probe the session bus for a running or activatable

Do not pin gnome-libsecret from Secret Service presence alone.
hasSecretService() only checks D-Bus names and activatable names. AppImage and deb metadata do not require libsecret-1.so.0, so the probe can succeed while libsecret cannot load.
Electron 44.9.3 supports KWallet backends. When explicit gnome-libsecret initialization fails, Chromium does not try KWallet. Electron then reports encryption as unavailable, and safeStorage.encryptString() and decryptString() throw.
This application's fallback writes new sessions as raw JSON with encrypted: false. Existing encrypted sessions become unreadable and are treated as absent. Gate the pin on a successful libsecret load. If libsecret is unavailable, leave password-store unset so Chromium can select KWallet or another available backend.

A Secret Service on the bus does not mean libsecret can load: the AppImage
does not ship it. An explicit gnome-libsecret that fails to load leaves
safeStorage without encryption instead of falling back to KWallet, so look
for libsecret-1.so.0 in LD_LIBRARY_PATH and the system library dirs first
and keep Chromium's default backend when it is missing.
@coderabbitai On the outside-diff finding (Do not pin gnome-libsecret from Secret Service presence alone): valid, addressed in 14dd821.
The pin now also requires libsecret-1.so.0 to be present. electron/libsecret.ts looks for it in LD_LIBRARY_PATH, then the multiarch, lib64 and lib system dirs. In main.ts the check is hasLibsecret() && hasSecretService(), so the file check runs first and the bus is only queried when libsecret exists. If it isn't found, --password-store stays unset and Chromium picks KWallet or whatever else is available, as it does today.
I went with a file lookup rather than loading the library: it never pins without the file, and a layout it doesn't know about (e.g. NixOS) just means no pin.
Separately, for the maintainers: the failing Lint, format, types, build, tests check is prettier on src/features/player/engine/playerEngine.ts, which this PR doesn't touch. main fails CI the same way at 30a2f0b.

@janisfox Confirmed in the inspected code: hasLibsecret() runs before hasSecretService(). If either check fails, the app leaves --password-store unset. An explicit user switch also remains unchanged. This addresses the original finding.
The file lookup is conservative for unrecognized layouts, as you described. It checks file presence, not whether the library can load.
I have not independently verified the reported CI failure on main at 30a2f0b.

What
On Linux, a login now survives switching between desktop environments or window managers (e.g. KDE ↔ GNOME ↔ Hyprland/sway), as long as every session uses the same Secret Service provider (see below). Before this, the app signed you out every time you switched.
Why
Both
auth/session.jsonandauth/youtube-session.jsonare encrypted withsafeStorage. On Linux, Chromium picks the keyring backend fromXDG_CURRENT_DESKTOP:kwallet5/6on KDE,gnome-libsecreton GNOME/XFCE/Cinnamon, andbasic_text(a hardcoded key) on everything else. Each backend uses a different key, so a session written under one desktop fails to decrypt under another.AuthSessionStore.read()then logsstored session is unreadableand returnsnull, and the next login re-encrypts the file with the new key. That breaks it for the first desktop too.How
electron/secret-service.tsasks the session bus (dbus-send,ListNames+ListActivatableNames, 1 s timeout) whetherorg.freedesktop.secretsis running or can be activated.electron/libsecret.tslooks forlibsecret-1.so.0inLD_LIBRARY_PATHand the system library dirs (multiarch,lib64,lib). The AppImage doesn't ship libsecret, and an explicitgnome-libsecretthat can't load leavessafeStoragewithout encryption instead of falling back to KWallet.electron/password-store.tspins--password-store=gnome-libsecreton Linux only when libsecret is installed, a Secret Service is there, and the user didn't pass their own--password-store. Otherwise Chromium's default backend stays, so nobody gets downgraded tobasic_textby this change (e.g. KDE with KWallet's Secret Service API turned off keeps the KWallet backend).electron/main.tsappends the switch beforeapp.ready, next to the other command-line switches. The same os_crypt key also encrypts Chromium's cookie store, so cookie-based logins are covered too.Requirement: one Secret Service provider across sessions
The pin means the app always fetches its key through the Secret Service API. The key lives in whichever program provides that API in the current session (gnome-keyring, KWallet 5.97+, KeePassXC…). If none is stored there yet, the app creates a new one. So:
