All Known Implementing Classes:

DefaultPasswordProvider, EnvironmentVariablePasswordProvider
```
@Deprecated
public interface PasswordProvider
```
Deprecated.

Implement this for different ways to (optionally securely) access secrets. Any further use case of extensible configuration/secrets must use DynamicConfigProvider interface. Users may still implement this interface for existing use cases till https://github.com/apache/druid/issues/9351 is resolved.
