If you have any third-party tool connected to Seller Central — a monitoring platform, a repricer, a PPC manager, an agency running your account — Amazon is about to ask you to reauthorize every one of them. Miss the window, and that tool’s access to your account expires. No grace period, no second email.
On August 10, 2026, Amazon retired the old “invite” process that services used to request access to a seller’s Seller Central account. In its place is a more direct flow: services listed on the Solution Provider Network get an “Authorise Now” button sellers can click straight from the listing, and services that aren’t SPN-listed share a unique authorization link directly with the seller.
That part is mostly invisible to you as a seller — it’s a backend change to how permissions get requested. The part that isn’t invisible comes next.
Amazon also made a related change worth knowing about: Seller Central now supports passkeys for account login, a separate but related tightening of who can get into your account and how.
Sept 3, 2026 is the deadline for services — not sellers — to verify their approved Seller Central roles inside the Solution Provider Portal. That’s the tool side doing its homework.
Your part comes after. Sometime in September, Amazon will email you directly, asking you to reauthorize each service currently connected to your account. This reauthorization doesn’t just refresh existing access — it replaces it. Every “secondary user” grant and every “authorized partner” grant you’ve ever handed out gets reset and rebuilt from scratch under the new system.

There are two separate ways this can quietly cost you a tool connection.
The first is on the provider’s end: if a service’s approved role set doesn’t match what it’s actually been using in your account, only the approved roles come back when you reauthorize. Anything outside that set is gone, and you may not notice until the tool stops updating.
The second is entirely on you: if you don’t reauthorize a service by the deadline Amazon communicates, that service loses all access to your account. Not reduced access — none.
This isn’t limited to one category of software. It covers anything with permissions into your Seller Central account: monitoring and intelligence tools, repricers, PPC and advertising managers, accounting and profit-tracking tools, and agencies managing your account on your behalf. If you’ve ever clicked “allow” for a third-party service, it’s in scope.
Agencies and multi-account operators have the most to lose here — one missed reauthorization can quietly cut off a tool across several client accounts at once, not just your own.
Three things worth doing now, before Amazon’s email shows up:
Make a quick list of every service currently connected to your Seller Central account. Most sellers underestimate this — it’s rarely just one or two.
Ask each provider directly whether they’ve verified their role coverage in the Solution Provider Portal ahead of Sept 3. A provider that hasn’t checked is a provider whose access might shrink out from under you.
When Amazon’s reauthorization email arrives, read it before acting on autopilot. It will look like routine account correspondence, which is exactly why it’s easy to skip.
SentryKit is one of the services that will go through this same reauthorization process with you. We’ve already verified our role coverage in the Solution Provider Portal ahead of the Sept 3 deadline, and we’ll flag it in-product when Amazon’s reauthorization request is expected to land, so it’s easy to recognize as legitimate rather than something to second-guess.
It affects any seller with at least one third-party service connected to Seller Central — which, in practice, is most active sellers using any kind of monitoring, repricing, advertising, or agency tool.
No. Sept 3 is the deadline for services to verify their own approved role coverage in the Solution Provider Portal. Sellers get a separate reauthorization request from Amazon in September.
If you don’t reauthorize by the deadline Amazon specifies in its email, that service’s access to your account expires entirely.
It shouldn’t, if it comes directly from Amazon — but because this is a new process, it’s worth confirming the request references a specific, familiar service name before clicking through.
Yes. This reauthorization replaces all prior access, including secondary user and authorized partner grants you’ve set up in the past, regardless of how long ago you set them up.
