Applications that are planned to be published in stores must be signed with a developer certificate. The signature guarantees that you are the developer of the application. The signature is always verified when the app is updated.
The signature must be stored in the same way as your password. If you lose your signature, you won’t be able to update your app anymore.
Signing an application is a mandatory procedure for applications of all platforms.
At the time of building the application in your Personal Account, you can choose our developer certificate for signing or use your own. To upload your signature, you need to go to the “Key manager” – “Add Signature” section, fill out the form and upload developer certificates. You can remove a developer’s signature at any time.
