Chrome extension support
Use the extension with the desktop app for browser save and fill flows.
Browser Extension
Use the extension with the app for safer everyday password flows.
The extension is not meant to replace the app. It works alongside the secure app experience for browser-based password entry and vault assistance.
Firefox extension support
Firefox support follows the same secure app-linked model rather than a browser-only vault model.
Additional browser support
Cross-browser support is planned as part of the same secure extension model.
