Create a Cox
Yahoo app password.
Cox moved all cox.net mailboxes onto the Yahoo Mail platform during 2025. You keep the @cox.net address, but sign-in now happens through Yahoo — so a Yahoo app password is what your mail app needs.
Applies to cox.net addresses.
Step by step
How to create your Yahoo app password.
- Sign in on the Yahoo Account Security page with your @cox.net address.
- Choose App Passwords, then Generate.
- Name the app and copy the code it produces.
- Use that code in your mail app in place of your normal password, with Yahoo's servers.
Worth knowing
- The old cox.net mail servers no longer apply — the Yahoo servers are the current ones.
