# 68007: Authentication Token Error

Log Type: TWILIO

Log Level: ERROR

## Description

This error occurs when Twilio cannot generate a Verify Push `AccessToken` for your request. The `AccessToken` resource authenticates client-side requests that enroll or register a Verify Push `Entity` or `Factor`, and the required `factorType` value currently supports only `push`.

### Possible causes

* Your request to `POST /v2/Services/{ServiceSid}/AccessTokens` included a `factorType` value other than `push`.
* Your application attempted to use the Verify Push `AccessToken` flow for a factor that is not part of the Push enrollment flow. The `AccessToken` resource is for Verify Push, while other Verify factors use their own `Factor` and `Challenge` resources.
* The request parameters do not match the supported Verify Push enrollment pattern, which requires a valid `identity` and a supported `factorType`.

### Possible solutions

* Set `factorType` to `push` when you create the `AccessToken`.
* Use the `AccessToken` resource only for Verify Push enrollment or registration in your client application.
* If you are building a non-Push Verify flow such as TOTP, switch to the factor-specific Verify API for that flow instead of the Push `AccessToken` flow. This follows from Twilio's Verify resource model, where `AccessToken` is documented for Push and `Factor` and `Challenge` are documented for Push and TOTP operations.
* Confirm that `identity` is an immutable identifier from your system and that you are creating the token under the correct Verify `ServiceSid`, then retry the request.
