# 70052: Public Key Client Validation Required For Account

Log Level: ERROR

## Description

The account is only allowed to perform Public Key Client Validation requests at Twilio. All other types of authentication are disabled for the account.

### Possible causes

* The Twilio-Client-Validation is not present in the request.

### Possible Solution:

* Ensure the Twilio-Client-Validation header is present in the request and valid.
* Disable forcing Client Validation feature at the Console if not needed.
