Amazon Says Seller Assistant Can Change Your Account: Who Has Access, and How to Audit It

On October 19, 2026, an Amazon moderator posted a "Seller Assistant Deep Dive" to the Seller Central forums. Most of it is a tour of what the AI assistant inside Seller Central can answer. The part worth your attention is a short section on who can use it, and one line in particular: Amazon tells sellers to "Only grant access to people you trust," because Seller Assistant "can view account data and make account-level, ASIN-level, and other changes."

That turns a routine settings page into a security decision. If someone on your team has the Seller Assistant permission, they have a tool that can act on your account, not just read it. Here is what Amazon has said about how access works, and a short audit to run on your Seller Central users.

Seller Assistant now acts, not just answers

Seller Assistant started as a way to ask questions in plain language instead of pulling reports. Amazon's forum post lists examples such as "why did my listing get suppressed?" and "how did my sales compare to last month?", plus policy questions, listing troubleshooting and account health checks.

The same post describes where it is heading. Amazon says Seller Assistant "now carries memory across your business" and "can take actions on your behalf when you ask it to, like opening a support case, with your approval and a log of every step."

Amazon went further in September. Its newsroom announcement of September 23 introduced Seller Assistant workflows, "custom automations that run continuously, monitoring conditions, interpreting changes, and responding dynamically, even when the seller isn't logged in to Seller Central." Amazon gives restocking and pricing adjustments as examples of routine tasks workflows can monitor and execute. For any workflow, Amazon says, "sellers choose whether it just surfaces recommendations or takes actions on their behalf. When it takes actions, sellers stay in control, reviewing and approving them before they're carried out." It adds that "Every action is logged with a complete audit trail."

Approval steps and audit logs are useful safeguards. They do not replace the earlier question: who on your account is allowed to use the tool in the first place?

Who has access by default

According to the forum post, "Seller Assistant access is managed through User Permissions, just like other tools in Seller Central." Amazon summarises the rules this way:

• Primary Users "have full access to Seller Assistant by default." There is nothing to switch on.
• Secondary users need the permission. "Your account's Primary User controls who gets access. Granting the Seller Assistant permission delegates its features and tools to that user."
• One exception to watch. "A secondary user with Multi-site Permissions can also grant themselves permission."

To grant access, Amazon gives this path: "User permissions → Edit next to the user → find Seller Assistant → turn on Edit access → Save Changes." It adds that "Changes take up to five minutes."

That third point is the one most sellers will not have thought about. If you gave someone Multi-site Permissions some time ago, Amazon's post says they can turn Seller Assistant on for themselves, without you granting it.

The permission has two layers

Amazon's post also explains that the Seller Assistant permission is not the whole story. In its words: "having the Seller Assistant permission lets you use it, but some individual actions also depend on your permission level for that specific area of Seller Central. Some actions are read-only, while others let you make changes."

So for some actions, what a user can do through Seller Assistant depends on two things: whether they have the Seller Assistant permission, and what they are allowed to do in the area of Seller Central the action touches. That makes your existing user permissions more important, not less. If a secondary user was given broad edit rights years ago for a one-off project and now also has the Seller Assistant permission, those edit rights are what the assistant has to work with when that person asks it to act.

A short user permissions audit

Amazon's general guidance on user permissions applies here too. In a November 2025 forum guide to user permissions, Amazon staff advised sellers to "grant the minimum permissions required for them to do their job" and to "Regularly review the permissions granted to your users," warning that "Users with account permissions who no longer work with your business could pose a risk to private information contained in your selling account."

With that in mind, here is a short audit to run:

1. List every user. Open User Permissions and write down each secondary user, what they do for you today, and what access they hold.
2. Remove anyone who has left. Former staff, past freelancers and old agency logins are the easiest risk to close.
3. Move outside contractors to Authorized Partners. Amazon's guidance says "All external contractor or companies that are not part of your company must be added as authorized partners," and "Do not add them as your secondary account users."
4. Decide who needs Seller Assistant at all. Grant it only to people you would trust to make the changes Amazon describes, and leave it off for everyone else.
5. Check who holds Multi-site Permissions. Amazon says those users can grant themselves Seller Assistant, so treat that permission as if it includes it.
6. Start workflows in recommendation mode. If you set up Seller Assistant workflows, Amazon lets you choose whether a workflow only surfaces recommendations. Begin there and review the results before you let a workflow take actions on pricing or restocking. Amazon's announcement says sellers review and approve actions before they are carried out, but before you rely on that, check in Seller Central which actions in your workflow wait for approval, what guardrails it has, and who on your team can approve.

Repeat the review whenever someone joins or leaves, and put a recurring reminder in your calendar for the rest.

Not every helper needs Seller Central

A lot of secondary users exist only so someone can see numbers: a bookkeeper checking profit, a VA preparing a weekly report, a PPC freelancer reviewing ad spend. If a person only needs to read results, they may not need a Seller Central login at all, and every login you do not create is one less user to audit.

That is one place an analytics tool helps. In SellerLegend, you can add team members with their own login through Guest Access, choose which SellerLegend features each person can open, and limit which marketplaces and account groups they see. Changes to a team member's access are logged. Your accountant can review net profit per product and your PPC freelancer can review advertising results, without either of them holding Seller Central permissions.

Key takeaways

• Amazon says Seller Assistant "can view account data and make account-level, ASIN-level, and other changes," and tells sellers to only grant access to people they trust.
• Primary Users have Seller Assistant by default. Secondary users need the permission, and Amazon says a secondary user with Multi-site Permissions can grant it to themselves.
• Some actions also depend on the user's permission level for that area of Seller Central, so broad edit rights given years ago matter more now.
• Seller Assistant workflows can run while you are logged out. Amazon lets you choose recommendations only and logs every action. Its announcement says sellers approve actions first, so check each workflow's approval settings before letting it act.
• Audit your users now: remove leavers, move contractors to Authorized Partners, and grant Seller Assistant only where it is needed.

If some of your users only need to see results, give them a login scoped to exactly what they need. Start a 21-day free trial of SellerLegend and add your team with the access each person needs.
