This is not an error - this is an interrupt that triggers device authentication when required due to a Conditional Access policy or because the application or resource requested the device ID in a token. This code alone does not indicate a failure on your users part to sign in. The sign in logs may indicate that the device authentication challenge was passed succesfully or failed.

AI generated answer (using internal Slack threads):

Based on the conversations, it appears that the Device ID feature in NetSuite is primarily used for user logins and is particularly applicable for the Suite Commerce InStore (SCIS) SuiteApp. It is used to apply restrictions to point of sale devices, specifically for the custom role set up by the SCIS app. However, this feature may not be suitable for restricting user logins from specific devices. For user login restrictions, IP address rules or restrictions are a more commonly supported option. Alternatively, Single Sign-On (SSO) can be used to manage logins outside of NetSuite. Once SSO is set up, direct NetSuite login for users can be disabled. However, it's important to note that Administrators and certain highly-privileged roles cannot be prevented from direct login. In the context of Two-Factor Authentication (2FA), it is required for certain role permissions. If a user tries to login to the UI with credentials that require 2FA but they haven't set it up, they will be prompted for a verification code. If they try to login using SuiteTalk web services, they will be told that the credentials are bad. When the 2018.2 2FA change was implemented, privileged users who didn't have 2FA configured were sent an email code to use upon their initial login. They had the option to defer the setup a few times. To bypass the need for a phone for 2FA, a browser extension can be used. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
