# **What’s in Passbolt 5.16.0?** Passbolt 5.16.0 introduces Offline Mode, allowing users to access their credentials when the Passbolt server is unreachable. ## **Offline mode (Beta)** During server maintenance, data center interventions, or network outages, teams lose access to critical credentials needed to restore systems, if those credentials are locked inside an unreachable Passbolt server. Offline mode closes this availability gap by providing secure read-only access to essential credentials when the server is unreachable. This ensures business continuity, satisfies compliance mandates for disaster recovery, and eliminates the need for insecure, stale manual exports. The administrator enables Offline Mode in the administration settings and can use Role-Based Access Control (RBAC) to refine which roles have access. ![Fig. Offline mode PRO admin settings](https://canada1.discourse-cdn.com/flex031/uploads/passbolt/original/2X/1/1eb5f98d2035a8debfcfaa74da123867450729c2.jpeg) Individual users allowed to access the capability can then select and mark specific resources within the application to make them available offline. ![Fig. Set resource as available offline from the More menu](https://canada1.discourse-cdn.com/flex031/uploads/passbolt/original/2X/1/1e3b4f8e6434179d460d697c36e5923aa2f8d50d.jpeg) Once marked for offline use, credentials can be accessed directly via the QuickAccess menu in the Passbolt browser toolbar. ![Fig. Viewing a password in offline mode](https://canada1.discourse-cdn.com/flex031/uploads/passbolt/original/2X/5/5f8b83eec173394487c4871b7e8cd6a9c15503ef.png) Offline storage is limited to a maximum of 1,000 resources per user. The feature currently supports only password and TOTP resource types with encrypted metadata. Upcoming releases will add support for other resource types and the ability to mark resources offline in bulk. ## **Security Considerations** Offline resources are accessible for **5 minutes** per session by default and encrypted information persists in browser storage for up to **7 days** without server connectivity. Passbolt Pro allows administrators to adjust both session durations and data retention limits to align with organisational compliance requirements. Once synchronised, credentials marked for offline access are cached on every browser connected to the same Passbolt account making them available across all devices. ## **Beta Testing** Because Offline Mode is in Beta and will be undergoing a third-party security review, it should be used for testing purposes only. A follow-up blog post covering its mechanics, limitations, and additional security considerations will be published soon. We welcome your feedback if you test it on a non-production instance. ## **Maintenance and security** As usual, this release ships a round of third-party dependency upgrades and security advisory fixes, with no user-visible impact. It also addresses minor bugs reported by the community. Check out the changelog for more information. ## **Conclusion** Many thanks to everyone who provided feedback, reported bugs, and contributed to making Passbolt better! ## **Changelog** **Platform** : Browser Extension & API **Name** : Enjoy the Silence | Browser Extension & API **Release notes** : [https://www.passbolt.com/changelog/api-bext/enjoy-the-silence-browser-extension-api](https://www.passbolt.com/changelog/api-bext/enjoy-the-silence-browser-extension-api) **Release Date** : September 17, 2026 **Song** : 🎶[Enjoy the Silence](https://www.youtube.com/watch?v=gI6fQ2IXMjE) 🎶 Enjoy Passbolt?

Is the beta for offline available for everyone? I just upgraded our CE installation to 5.16.0 and the Offline mode button show up in the Organisation Settings menu but when I click on it I got a full blank page and not the one shown. ---

I am experiencing the same issue on firefox. I believe it is because the firefox add-on is still on version 5.15.1. I have checked the Firefox add-on store, 5.15.1 is the latest available version… If i use another Browser (eg. Brave), I am able to set up the offline mode and use it normally. Is there an issue with the add-on update on Firefox? Anything I can do to help? ---

Hello, Yes firefox 5.16 is still in review. Unfortunately there is not much we can do apart from inviting you to use another browser. Best, Remy
