Authentication Methods {#uc-authentication-methods}
===================================================

`Cybersource` recommends that you review the response in the transient token and compare it with the information below in order to determine the authentication status. For more information about transient tokens, see [Transient Tokens](/docs/cybs/en-us/digital-accept-flex/developer/all/rest/digital-accept-flex/uc-intro/uc-tokens-intro.md ""). This table describes the possible authentication results and the associated processingInformation.commerceIndicator.value field values in the transient token.

|---------------------------|------------------------------------------------------------------------------------------------|
| Successful authentication | processingInformation.commerceIndicator.value field value set to `VBV` in the transient token. |
| No authentication         | No commerce indicator in transient token.                                                      |
