Inactive secondary users to be removed from Seller Central accounts
To better protect your Seller Central account and keep your data secure, each quarter we’ll remove secondary users on your account who are inactive for more than 12 months.
This change offers you the following:
Increased security: The removal of inactive users reduces potential access risks by bad actors and improves account safety.
Simplified access management: Helps you manage permissions more efficiently and helps prevent any unauthorized access.
