On the Sinch Authentication 365 web-based Administrative UI, the user will be able to set configurations for default values that will apply to the API calls. The purpose of this feature is to enable the administrator of the 2FA implementation to change common features via the UI, rather than having to re-code the APIs to change features and configurations.

Businesses may use multiple sub-accounts for their own reseller customer or different use-cases, with each account or sub-account having different default configurations.

To view (and modify) Account Information, click the Accounts menu from the Authentication 365 web-based Administrative UI. This is where you can set defaults for your account. Of course, any default may be overridden through options in the API calls. The Account Info page displays four sections:

  • Account Information
  • Token & Callback Configuration
  • URL Authorization Configuration
  • 2 Step URL Authorization Configuration

This page displays the following information about your account and your account settings.
