How to Use 3uTools IPA Signature.
Step 1: Open 3uTools and go to the “Toolbox” section, then look for “IPA Signature.”

Step 2: Click on “Add IPA File” and choose the IPA file you want to sign.

Step 3: Click on “Import Certificate” and select the certificate and description file for signing. Then, enter the certificate password to proceed.

Step 4: Once you’ve added the IPA and certificate files, choose where you want to save the signed files based on your preference.

Step 5: Double-check the IPA file and certificate, then click “Start Signing” to begin the process.

If you don’t have a certificate file, you can still sign the IPA using your Apple ID by following these steps.
Use the Signing method with Apple ID:
Step 1: Click on “Sign with Apple ID” and enter your Apple ID and password. Then, select or enter the device ID for the iPhone or iPad where you’ll install the signed IPA file.

Step 2: After verifying, click “Confirm.” Make sure your iOS device is connected to 3uTools so it can read the device ID (UDID). If it’s not connected, you’ll need to enter the device ID manually. Once your Apple ID is added, the signing details will appear in the list below.

Step 3: Next, add the IPA file you want to sign. Verify both the IPA file and the Apple ID used for signing, then click “Start Signing.” After the signing process is complete, you can install the app using 3uTools. Once installed, go to “Settings > General > Profile” and trust the app before opening it on your iOS device for the first time.

Please note that the signed IPA file may be saved in a different location than the original. After signing, just click on the “Open Signed IPA Location” button to find all your signed IPA files, ready for installation.
