Is there any secure local service that one should use for storing and retrieving organization wide application passwords?

Therefore I need some way to dynamically retrieve a password from my secure store/bucket and pass it as variable in authentication information , instead of hard-coding it in my scripts. 
Storing application passwords in central location
scripting;security;password
