# Redacting sensitive information from change types
<a name="ct-redaction"></a>

AMS change type schemas offer a parameter attribute, `"metadata":"ams:sensitive":"true"` that is used for parameters that would contain sensitive information, such as a password. When this attribute is set, the input provided is obscured. Note that you cannot set this parameter attribute; however, if you are working with AMS to create a change type and have a parameter that you would like obscured at input, you can request this.
