Single sign-on (SSO) is launched on the Amazon Seller App! If you have cross-regional accounts, use SSO to reach all of your marketplaces and linked accounts with any set of account credentials. Then you can use the marketplace switcher that is located at the left navigation menu to alternate between your marketplaces.
SSO on mobile is already in effect if you have linked your accounts. If your accounts are not linked, visit linking accounts here and follow the instructions.
If you don’t have Amazon Seller App, you can download it for free from the links below.
