IF you're able to build your app from a PC, but you don't recall the password, here's what you can do to retrieve the password:

Method 1:

In your build.gradle, add println MYAPP_RELEASE_KEY_PASSWORD as below:

signingConfigs {
    release {
        if (project.hasProperty('MYAPP_RELEASE_STORE_FILE')) {
            storeFile file(MYAPP_RELEASE_STORE_FILE)
            storePassword MYAPP_RELEASE_STORE_PASSWORD
            keyAlias MYAPP_RELEASE_KEY_ALIAS
            keyPassword MYAPP_RELEASE_KEY_PASSWORD
            println MYAPP_RELEASE_KEY_PASSWORD
        }
    }
}

After that, run cd android && ./gradlew assembleRelease

Method 2:

Run keytool -list -v -keystore your <.keystore file path> e.g. keytool -list -v -keystore ./app/my-app-key.keystore.

It will ask for you to Enter keystore password: Just press enter key here. and you will be able to find mapped to Alias name:

Then, run grep -rn "" . in your terminal and you will be able to see your signing.json file as below:

./app/build/intermediates/signing_config/release/out/signing-config.json

The file will have your password in json format with key "mKeyPassword":" < your password > "
