iOS 14 and later, including the latest iOS 18.x versions. Both iPhone and iPad are supported.

Yes. When you upload your own certificate for web signing, the files are deleted from the server immediately after signing completes. UnKeySign does not store, log, or share your P12 password or provisioning profile. Signed IPA files are auto-deleted within 10 minutes.

A P12 file (.p12) is a PKCS#12 archive containing your Apple Developer signing certificate and private key. You export it from Keychain Access on Mac or receive it from a certificate provider. It's protected by a password.

A provisioning profile (.mobileprovision) links your certificate to specific devices (via UDID) and app bundle IDs. It tells iOS which devices are authorized to run the signed app. You create it in the Apple Developer portal.

Common causes: (1) your device UDID is not in the provisioning profile, (2) the certificate is revoked, (3) the provisioning profile has expired. Check with your certificate provider.

The web signing service signs the official UnKeySign app. To sign custom IPA files, install UnKeySign on your device and use the in-app signing engine.

No. Web signing works from any device with a browser. The iOS app handles signing on-device. You only need a Mac if you want to export P12 certificates from Keychain Access.
