Yahoo! JAPAN Ads

As previously announced in "Yahoo! JAPAN Ads: Details of integrated "Business ID"", we would like to inform you about the discontinuation of sign-in using one-time passcodes and the discontinuation of the Business ID switching feature in the Campaign Editor.

May 31, 2026 (Sunday)
*The schedule is subject to change.

We previously informed you that the sign-in method using one-time passcodes would be discontinued around March 2026. However, in consideration of the current usage status, we have changed the discontinuation date as stated above.
After the discontinuation date, sign-in using one-time passcodes will no longer be available. Please complete the Business ID integration as soon as possible.
For the integration procedure, refer to "How to integrate Business ID."
Please note that once you integrate your Business ID, one-time passcodes can no longer be used. After integration, please sign in using the business account of your LINE Business ID. By setting up a business account, you will be able to sign in with your registered email address and password.
For setup instructions, please refer to "How to sign in with a LINE Business ID."
Customers who currently use only one-time passcodes for sign-in will be required to complete Business ID integration and set up a business account after the discontinuation.

March 10, 2026 (Tuesday)
*The schedule is subject to change.

We have determined the discontinuation date of the feature that allows you to register and switch between multiple Business IDs in the Campaign Editor as stated above.
If you have registered multiple Business IDs, invite the relevant Business ID to your advertising account before the discontinuation date so that the account can be operated with a single Business ID. For detailed instructions, refer to "Invite other users to your account."
Data downloaded to your local environment in the Campaign Editor will remain available after the discontinuation date. If you wish to continue using it, uncheck "Settings" > "Sign-in Information" > "Save sign-in information" (this will change the setting to require sign-in each time).
By signing in again, you can continue to use the data in your local environment.
