    No, an app cannot be updated if you do not have its author certificate. When updating an app in Seller Portal, the author certificate of the original binary and its updated binary must match. If the certificates do not match, you cannot register the updated binary in Seller Portal.

    If you are only going to use the emulator or if you are only going to distribute your app in Galaxy Store, you only need one (primary) distributor certificate.

    If you are going to distribute your app in another app store, you can provide a secondary distributor certificate for that app store.

    In your certificate profile, you can have up to two distributor certificates:

    • The primary distributor certificate is automatically generated for you when you create your certificate profile (this certificate is also referred to as a personal distributor certificate). The personal distributor certificate is for development purposes only. When you publish your app to Galaxy Store, the primary certificate is replaced by Galaxy Store’s distributor certificate.

    • The secondary distributor certificate is optional and must be a valid non-personal distributor certificate. The secondary distributor certificate is typically the distributor certificate of another app store. When you publish your app to Galaxy Store, the secondary certificate is retained.
      Do not add a secondary personal distributor certificate. If you add a secondary personal distributor certificate to your certificate profile, it is not replaced when the app is published to Galaxy Store. This certificate will be validated when the app is installed on a device. If this certificate is not valid (for example, it has expired), the app will not install on the device.
      If you have added a secondary distributor certificate that is a personal distributor certificate, remove it from your certificate profile.

    Note: Seller Portal validates the primary distributor certificate only. A device validates all personal distributor certificates.

    No, using the Certificate Manager in Tizen Studio, you cannot reset a certificate's password. If you forget the password for your author certificate, you must regenerate a new author certificate. You will not be able to publish updates to any app published with the original author certificate. If you want to publish updates to your apps that used the original author certificate, you must republish the original apps using the regenerated author certificate.
