iCloud Passwords

iCloud Passwords lets you fill passwords from iCloud Keychain when signing in to websites using Firefox.

The iCloud Passwords Chrome extension allows you to securely autofill passwords stored in your iCloud Keychain when signing into websites using Firefox. It not only fills existing passwords but also saves any new passwords you create directly to your iCloud Keychain, ensuring seamless synchronization across all your Apple devices. Additionally, the extension supports generating verification codes by right-clicking on QR codes, enhancing your two-factor authentication process.

Designed exclusively for macOS Sonoma or later, iCloud Passwords offers a smooth and secure password management experience for Firefox users within the Apple ecosystem. Note that it is currently unavailable for Windows users.

User reviews

The iCloud Passwords add-on for Firefox is helpful for autofilling passwords when it works but suffers from significant issues. Multiple users report high CPU usage, memory leaks, and major slowdowns in Firefox performance. It often stops functioning after Windows or macOS updates and mostly supports Chrome and Edge officially, making it unstable for Firefox users. The add-on also sometimes fails to remember passwords properly, leading to frustration among users. Overall, it has usability but is plagued by performance and compatibility problems.
Pros
  • Able to fill in passwords when functional
  • Better than having no password manager integration
  • Worked well before recent OS updates
Cons
  • Causes high CPU usage and memory leaks on some sites
  • Slows down page loading and scrolling significantly
  • Stopped working on Windows and some macOS versions after updates
  • Frequently unresponsive or fails to remember passwords correctly
  • Only officially supports Chrome and Edge, making Firefox support unstable

This had been working on Windows until a couple weeks ago, when it suddenly told me it would only work on Chrome or Edge. I use Firefox on my Windows machine to get away from chromium. I may need to switch back to Bitwarden on my Apple and Windows devices instead of using Apple Passwords, which is disappointing.

Works great and even supports 2FA codes.
