What is Store Password in Android CloudBuild?

I’m trying to set up my credentials in CloudBuild. I am at the Android Credentials window and I have no idea what “Store Password” is. Unity Asset Store? Google Developer Password? Google Play Password? I’ve tried them all, nothing is working. I can’t find any explanation as to what it’s wanting. Can someone give me a hint? Thanks.

Could it be referring to the password for the Android Keystore file that is used to sign the application? Not used CloudBuild myself So i’m unsure if keystore signing is necessary or optional
