method to supply password for data source connection dynamically instead of using config/environment variables

[Rushikesh-Mule]

I am currently using loopback 3 but for security reasons I don't want to store password in config or environment variables so my approach is to get secret password from some API and pass it to framework at runtime while making data source connection. so looking for any solution to pass password at runtime to connection methods w.r.t loopback 3/4.
Thanks
