What certificate does Feather need?
Feather needs a .p12 signing certificate, the .p12 password, and a matching .mobileprovision profile that contains your device UDID. CertDrop delivers the complete device-matched package for $8 so it can be imported directly into Feather.
What is a Feather certificate?
There is no separate certificate format made only for Feather. Feather uses the same Apple signing assets used by other compatible IPA signing tools.
The .p12 packages the signing identity and private key, while the matching .mobileprovision profile defines the permitted device and signing rules. Feather also needs the password that protects the .p12 file.
CertDrop prepares these files for the UDID submitted with the order, so you can import them into Feather and sign compatible IPA files directly on the registered device.
Moved to a new iPhone 18 Pro or Pro Max? Feather needs certificate files matched to the new phone's UDID. See the iPhone 18 Pro / Pro Max certificate page.
