As Trellix continuously works to improve the security of our products, we are changing how the credentials work for the Trellix API. We are moving from using a username and password to a Client ID and Secret that are much more secure and can also be revoked at any time, should they be compromised.
If you are using the Trellix API, please make this change as soon as possible to ensure your access continues to be secure.
For more details, see the article Trellix API credentials changing from username/password to Client ID/Secret.
