Last year, westarted requiringmulti-factor authentication in Microsoft Advertising online. Multi-factor authentication is a security process thatrequiresyou to verify your identity in two different ways. Starting in April we will require multi-factor authentication for all users who sign in through a third-party application that uses the Bing Ads API.
[MARCH 25th UPDATE: Over the last several months most API clients have prepared for the enforcement of MFA. Due to a new developer requirement as explained in a new post, we are extending the deadline from April 1st to August 1st, 2021.]
What users need to do:When you sign in and allow third-party applications to access your Microsoft Advertising account , you’ll be asked to provide a second form of verification that matches contact information in your Microsoft account profile. You must check your Microsoft account settings now to ensure that your security information is up to date.
What developers need to do: Upon enforcement of multi-factor authentication, if your users have not setup multi-factor authentication the Bing Ads API will not accept any access tokens that you obtain or have already obtained on the user’s behalf.We recommend that youinform and guide users to complete multi-factor authentication in advance.
