I'm working on Android Stuido to generate a signed certification, but from the New Key Store option, I need to create two passwords for this certification. Do you know where the difference between them is?

    IMO you can read here [Signing in Release Mode](https://developer.android.com/tools/publishing/app-signing.html). I think key store is like a container that contains private key, both need to be kept secure. So need 2 passwords. You can read `Securing Your Private Key` section at that link – BNK Aug 31 '15 at 04:51

Keystore is a binary file that contains a set of private keys.

Private key represents the entity to be identified with the app, such as a person or a company.

So Keystore password is used to open a keystore and simple password is password of private entity stored in keystore file..!! check here

    When using jarsigner it only asks for one password - I assume this is the key store password so why does Android Studio's Build -> Generate Signed APK require another password? – Marc Mar 16 '16 at 15:11

    Yes, we signed our Android .apk app with jarsigner and one password. Android Studio "demands" two. – Marc Mar 23 '16 at 14:54
  • Am I correct that both the keystore password and the simple password only exists on your local computer, but neither gets sent with the app to the app store? – kojow7 May 01 '18 at 20:07

Key Store password is like master password of other key's Multiple key pairs can be store within a key store. when you try to reuse that key android studio will ask you for key store password.

As the name suggest the key store is a collection of private and public keys. One can have multiple pairs of public and private keys within a key store.

In simpler terms key store is the directory which holds the key.
