title: How long is validity of app signing key when I 'Let Google create and manage my app signing key'?
body: <p>When we create an app signing key for Android app, we set <a href="https://developer.android.com/studio/publish/app-signing#generate-key" rel="nofollow noreferrer"><strong>Validity (years)</strong></a> which should be valid for at least 25 years. For example, I can set it for 100 years.</p>
  <p>But past few years, we were introduced <a href="https://developer.android.com/studio/publish/app-signing#app-signing-google-play" rel="nofollow noreferrer">Play App Signing</a>. If I create just the upload key (and not create the app signing key by myself), <a href="https://developer.android.com/studio/publish/app-signing#enroll_new" rel="nofollow noreferrer">Google creates and manages the app signing key</a>.</p>
  <p>Then, I wonder how long validity of app signing key created by Google is? I want it at least for 100 years. Isn't it for 25 years? What will Google do when app signing key expires?</p>
