Unable to Switch to a Different Bandai Namco ID on a Shared Device Even After Signing Out of the Service

If you would like to use a different Bandai Namco ID, please first log out of the Bandai Namco ID Portal, then sign in to the service again.

Even after you log out of the service, your Bandai Namco ID session may still remain active in your browser.
If you attempt to sign in to the service again while this session is still active, you may be automatically signed in with the Bandai Namco ID that was previously used.
As a result, if multiple people share the same device, you may not be able to switch to a different account.

If multiple people share the same device and each person needs to use their own Bandai Namco ID, we recommend using your operating system's user account feature (such as Multiple Users on Android) or your browser's profile feature (such as Safari Profiles).
The availability of these features depends on your operating system, browser, and device.

Please note that each individual should use only one Bandai Namco ID account.
If multiple Bandai Namco IDs are being used on a shared device, please make sure the correct account is selected when signing in.
