iCloud Passwords — Apple Inc.

iCloud Passwords lets you securely fill passwords from iCloud Keychain when signing in to websites using Firefox. Any new passwords you create in Firefox are saved to your iCloud Keychain so that they are also available across your Apple devices. The extension can also generate verification codes, which you can set up by right-clicking on a QR code.

The iCloud Passwords extension is compatible with macOS Sonoma or later, and Windows versions supported by the iCloud for Windows app. To enable the extension on a PC, download the iCloud for Windows app from the Microsoft Store and enable iCloud Passwords.
