Bitwarden for Safari

Safari's extension model differs from Chrome and Firefox — extensions ship inside macOS apps. The Bitwarden Safari extension is bundled with the Bitwarden Mac app.

Why is the Safari extension bundled with the app?

Apple's Safari Web Extensions API (introduced in Safari 14) requires extensions to ship inside containing macOS apps — there's no Web Store equivalent for Safari. Installing the Bitwarden app from either the Mac App Store or the .dmg installs the extension at the same time.

Enable the extension after install

1. Install Bitwarden Mac app (Mac App Store or .dmg).
2. Launch Bitwarden once — this registers the extension with Safari.
3. Open Safari → Settings → Extensions tab.
4. Find Bitwarden in the left sidebar, tick the checkbox.
5. Click the Bitwarden icon in Safari's toolbar. First time, it asks for site permissions — choose Always Allow on Every Website for autofill to work universally.

Safari on iOS / iPadOS

iOS Safari supports Safari Web Extensions too. Install the Bitwarden iOS app, enable the extension under Settings → Safari → Extensions → Bitwarden. Then in Safari, the Bitwarden icon appears in the address bar's "aA" menu.

Safari extension caveats

• Safari has the strictest extension sandbox among major browsers — some autofill flows on iframe-isolated forms work better on Chrome/Firefox.
• The Bitwarden Safari extension can't auto-update independently — it updates with the Bitwarden Mac app updates.
• Per-site permissions reset if you uninstall and reinstall the app; you re-grant "Always Allow" on first use.
