Using automatically managed credentials
For your app to be distributed in an app store, it needs to be digitally signed with credentials such as a keystore or a distribution certificate. This certifies the source of the app and ensures that it can't be tampered with. Other credentials, such as your Apple Push Key and FCM API Key, are needed to send push notifications, but they are not involved in app signing.
Thankfully, that's all that you need to know about any of this to build an app with EAS Build, but if you would like to learn more you can refer to the "App Signing"
Are you using the classic build system? (
Read on to learn how EAS can automatically manage credentials for you and your team.
When you run
eas build, you will be prompted to generate credentials if you have not done so already. Follow the simple instructions to generate your credentials. Where needed, they will be stored on EAS servers. On subsequent builds of your app, these credentials will be re-used unless you specify otherwise.
Generating your iOS credentials (distribution certificate, provisioning profile, and push key) requires you to sign in with an Apple Developer Program
If you have any security concerns about EAS managing your credentials or about logging in to your Apple Developer account through EAS CLI, please refer to the "Security"
guide. If that does not satisfy your concerns, you can reach out to firstname.lastname@example.org
for more information, or use local credentials
If you haven't set up your Push Notifications key yet, EAS CLI will ask you to set it up during the next
eas build run.
If you're building an app that was previously built with classic builds (
expo build:ios), then you already have iOS push notification credentials configured on Expo's servers, so there's nothing you need to do.
You can also set up the Push Notifications key with the
eas credentials command. Run it, select
Push Notifications: Manage your Apple Push Notifications Key, and then choose the appropriate option to set up the key.
The Android push notification credentials setup for EAS Build is identical to the setup you might've used for classic builds (
expo build:android). If you've already configured your app with FCM, there's nothing else you need to do.
If you haven't, please run
eas credentials, select
Push Notifications: Manage your FCM Api Key, and then choose the appropriate option to set up the key.
After you have generated your iOS credentials, it's no longer necessary to have access to the Apple Developer team in order to start a build. This means that your collaborators can start new iOS builds with only their Expo accounts.
