# Automatically Re-Signing iOS Apps

Sofy provides testers with the ability to **automatically re-sign** IPA files with internal provisioning files. To enable this feature, complete the following steps:

- Upload your App (IPA) from **Add Application**.

- **Select your app**. In the **General Settings** of your app, note that **"automatically sign provisions for new uploads"** is checked by default.

- If you don’t want Sofy to sign your App (IPA), you can uncheck the **"automatically sign provisions for new uploads"** and then press the **"Update" button**.

- Now, from the **Sofy Device Lab**, **select any device** you want to test your app on.
- After opening your device from lab, if your IPA is not embedded with Sofy’s device list, app installation will fail and you will see an error: Got error "`ApplicationVerificationFailed` with code 0xe8008029: Failed to verify code signature of /var/installd/Library/Caches/com.apple.mobile.installd.staging/temp.eGuIL3/extracted/Payload/YourAppName : 0xe8008029 (The code signature version is no longer supported.)"

At this point your app will be signed with Sofy’s certificate, and the re-signed app will be replaced in your account. Please note that everything will be available in Logs (status).

- Now your app will be installed on the device you acquired!

Please note: This will be a one time process and your re-signed IPA will work on all the other devices.

- The checkbox for **"automatically sign provisions for new uploads"** will be set to **true** for all upcoming builds. If you don’t want your future builds to be signed by Sofy’s certificate, you can uncheck the check box explicitly from the **build settings menu**.

- **Already previously uploaded an iOS build and/or a signed build?** If you have already have signed IPA with their own provisions, then Sofy will _not_ re-sign.  If you're an existing customer who _does not_ want to re-sign:
  - Navigate to **App Manager Select** in the application
  - Uncheck **"Automatically sign provisions for new uploads"**.
