Signing keys are digital certificates that prove you're the developer of your app. Both Android and iOS require signing keys before you can publish. AppMyWeb stores your keys securely and uses them automatically when building.

🔑 Critical Requirements: Valid signing keys + Launch icon uploaded (1024×1024 PNG) = Ready to publish

Go to Services → Key Manager in your app dashboard.

Android Keystore

Android apps must be signed with a keystore to be published. This digital signature proves you're the developer and allows users to receive updates. AppMyWeb can generate one for you automatically, or you can upload your existing key if you've already published on Google Play.

Option 1: Generate New Key (Recommended)

⚠️ Critical: If you lose your keystore, you cannot update your app on Google Play. Backup immediately!

Let AppMyWeb generate a keystore for you automatically:

1️⃣

Click CREATE KEY Blue button at top right

2️⃣

Enter List Name A name for your key

3️⃣

Keep Toggle OFF "Upload custom key" should be OFF

4️⃣

📝

📁

Upload .jks File Drag or select your keystore file

💾

Click SAVE KEY Upload and save your keystore

iOS API Key

Unlike Android, iOS requires an API Key that connects to your Apple Developer account. This allows AppMyWeb to publish and upload your app directly to App Store Connect on your behalf. The key is created once and can be used for all your iOS apps.

Step 1: Create API Key in Apple Developer

This step gives AppMyWeb permission to upload app files to your Apple account. You only need to do it once.

ℹ️ Requirement: You need an Apple Developer account ($99/year).
