# Make settings secret

**Requires**: [abstractions module](/configuration/modules/abstractions.md).

By default settings are subject to [logging](/configuration/basic-scenarios/log-new-settings.md), which is generally not appropriate for secrets. This can be fixed either by disabling logging entirely on the [configuration provider](/configuration/concepts-and-basics/configuration-provider.md) or by annotating fields and properties of the model with `[Secret]` attribute:

```
class MySettings 
{
    [Secret]
    public MySecrets Secrets { get; } = new MySecrets();
    
    public TimeSpan Timeout { get; } = TimeSpan.FromSeconds(30);
    
    [Secret]
    public string EncryptionKey { get; }
}

class MySecrets 
{
    public string ApiKey { get; }
    public string Login { get; }
    public string Password { get; }
}
```
