How to Give an Agency Access to Amazon, Walmart and TikTok Shop Safely
The first practical step with any marketplace agency is giving them access to your accounts, and it is also where many brands take unnecessary risks. Sharing your main login and password can expose bank details, tax information and two-step verification codes, and makes it hard to see who did what. Amazon, Walmart and TikTok Shop all have built-in ways to invite users with limited permissions. Here is how each one works and what access an agency actually needs.
Why you should never share your password
- Control. A user invitation can be limited, changed or removed in seconds. A shared password means changing it, and updating two-step verification, every time someone leaves.
- Accountability. Separate users let you see which person or company made a change.
- Responsibility. Walmart says plainly that sellers are responsible for their users' actions, according to Walmart Marketplace Learn (updated Jul 2, 2025). The same logic applies on every platform: whatever happens in your account is on you.
- Sensitive areas stay private. On TikTok Shop, some areas are only visible to the shop owner's account "for safety reasons," per TikTok's Seller Center roles guide (updated Aug 2025).
How each platform handles user access
| Platform | Where to invite | Permission options | Kept by the owner |
|---|---|---|---|
| Amazon Seller Central | Settings → User permissions (primary account holder) | Access level set separately for each area of Seller Central | Primary user controls permissions; Amazon itself "cannot grant permissions" |
| Walmart Seller Center | People and permissions → Add User (Admins only) | 3 roles: Admin, Read and Write, Read Only | Walmart advises limiting Admin to people who can accept binding terms for your company |
| TikTok Shop | Business Center → Accounts → Shops → assign member or partner | 8 Seller Center roles, e.g. Main Administrator, Advertising Manager, Finance Specialist | User management, account details, bank accounts, tax info and linked TikTok accounts |

Amazon
Only the primary account holder of a Professional selling account can grant access. In an Amazon Seller Forums reply, an Amazon staff member explained that you open Settings, choose User permissions, enter the new user's details and send an invite. Once the user accepts the email link, you set their access level for each area of Seller Central. The staff member also noted that "Amazon cannot grant permissions," so this always has to come from you.
Walmart
Walmart offers three roles, according to Walmart Marketplace Learn. Admin has full access, including generating API credentials, requesting special category approvals, creating users and accepting binding legal agreements. Read and Write covers day-to-day work like setting up items and viewing reports. Read Only can view data and download reports but cannot change anything. Only Admins can add users.
TikTok Shop
TikTok Shop members are added through TikTok Business Center, where you can assign a member or a partner to your shop and pick their permissions, per TikTok's Business Center help article. Seller Center has eight roles. Even the Main Administrator role cannot see user management, account information, bank accounts, tax information or linked TikTok accounts; those stay with the shop owner.
What access an agency actually needs
- Full channel management: listings, inventory, pricing, orders, ads and reports. On Walmart that usually means Read and Write; on TikTok Shop, roles such as Product Management, Advertising and Order Fulfillment, or Main Administrator if they run everything.
- Ads only: advertising and reporting access, without finance or account settings.
- Reporting or audits: view-only access.
- Almost never: bank account, tax settings, user management, or the ability to accept legal agreements. Keep these with an owner or an officer of your company.
Grant the smallest role that lets the agency do the job, then expand it if a task really requires more. It is much easier to add permissions than to undo a mistake.
Access checklist
- Turn on two-step verification for your own owner account first.
- Invite each agency team member with their own work email, never a shared login.
- Choose the lowest role that covers the agreed scope of work.
- Keep bank, tax and user-management settings with your company.
- Write the access scope into your agency agreement.
- Review users every quarter and remove anyone who no longer needs access.
- When a contract ends, remove all agency users on the same day.
