What is the keyPassword I am supposed to use for signing a React Native project?

I have made an app project in React Native, and I want to build its apk. I am following the official documentation as shown here https://reactnative.dev/docs/signed-apk-android.

It says that I must first generate a private signing key using keytool. I have followed the instructions for windows. Here is the terminal output:

PS C:\Program Files\Java\jdk1.8.0_271\bin> keytool -genkeypair -v -storetype PKCS12 -keystore my-upload-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
Enter keystore password:
Re-enter new password:
What is your first and last name?
  [Unknown]:  My Name
What is the name of your organizational unit?
  [Unknown]:  Myself
What is the name of your organization?
  [Unknown]:  OrgName
What is the name of your City or Locality?
  [Unknown]:  CityName
What is the name of your State or Province?
  [Unknown]:  StateName
What is the two-letter country code for this unit?
  [Unknown]:  XY
Is CN=My Name, OU=Myself, O=OrgName, L=CityName, ST=StateName, C=XY correct?
  [no]:  yes

Generating 2,048 bit RSA key pair and self-signed certificate (SHA256withRSA) with a validity of 10,000 days
        for: CN=My Name, OU=Myself, O=OrgName, L=CityName, ST=StateName, C=XY
[Storing my-upload-key.keystore]
PS C:\Program Files\Java\jdk1.8.0_271\bin>

Immediately after this, the documentation says I must enter the generated keystore password and key password into this file

  1. Place the my-upload-key.keystore file under the android/app directory in your project folder.

  2. Edit the file ~/.gradle/gradle.properties or android/gradle.properties, and add the following (replace ***** with the correct keystore password, alias and key password),

MYAPP_UPLOAD_STORE_FILE=my-upload-key.keystore
MYAPP_UPLOAD_KEY_ALIAS=my-key-alias
MYAPP_UPLOAD_STORE_PASSWORD=*****
MYAPP_UPLOAD_KEY_PASSWORD=*****

Later, in android/app/build.gradle, I am to add this:

signingConfigs {
        release {            
            storeFile file(MYAPP_UPLOAD_STORE_FILE)
            storePassword MYAPP_UPLOAD_STORE_PASSWORD
            keyAlias MYAPP_UPLOAD_KEY_ALIAS
            keyPassword MYAPP_UPLOAD_KEY_PASSWORD
        }
    }

I believe the "storePassword" is the "keystore password" which I created earlier when i was prompted by keytool, but I do not remember ever seeing or generating a "keyPassword".

Perhaps this is a banal question, but how do I find my "keyPassword"? Even other tutorial websites seem to assume the user already has it or knows it. Is the "keyPassword" something that I must create right now?

If Keytool CLI didn't ask for key password explicitly then it is same as the store password which it asked for.

You can also create the key using command line:

keytool -genkey -v -keystore debug.keystore -storepass android -alias androiddebugkey -keypass android -keyalg RSA -keysize 2048 -validity 10000

Then you need to add the key inside android/app folder and add the keystore name inside android/app/build.gradle file, in the signingConfigs configuration.

In Android Studio go Build -> Generate Signed Bundle / Apk. You will see button Create New on second step. There you will be able to create key with password
