Fix the AWS CloudShell ‘Account Verification’ Error

Why the “Account Verification In Progress” message appears

When you launch AWS CloudShell for the first time, the console may pause on a banner that reads Account Verification In Progress. It’s not a bug so much as a safety check – AWS is confirming that the underlying account meets the requirements for a fully functional shell environment. The message often shows up right after a new account is created, after an organization switches its root user to an IAM role, or when a recent policy change affects CloudShell permissions.

During this brief window, the service is synchronizing with your Identity and Access Management (IAM) settings, validating email ownership, and sometimes waiting for compliance checks to finish. Most users see the status resolve within a few minutes, but a handful encounter a stubborn stall that blocks access altogether.

Step‑by‑step guide to clear the verification block

Below is a practical checklist that covers the most common culprits. You don’t need deep expertise – just follow the order and you’ll usually be back to a working shell in under half an hour.

• Confirm email verification. AWS sends a verification link to the email address associated with the root user. If you missed it, request a new one from the IAM security credentials page. The CloudShell service won’t finish its check until the address is confirmed.
• Review IAM permissions. CloudShell requires the managed policy AWSCloudShellFullAccess (or an equivalent custom policy). Navigate to the IAM console, locate the user or role you’re using, and ensure this policy is attached. Missing permissions are a frequent source of the “in progress” loop.
• Check regional availability. CloudShell is currently supported in most, but not all, AWS regions. If you launched the console in a region where CloudShell is still being rolled out, the service may stay in verification mode. Switch to a supported region like us-east-1 or eu-west-1 and try again.
• Clear browser data. Stale cookies or cached authentication tokens can confuse the verification handshake. Open a private/incognito window, or clear cookies for console.aws.amazon.com, then reload CloudShell.
• Disable SSO temporarily. If your organization uses AWS Single Sign‑On (SSO), the verification process can clash with token propagation. Log out, sign in directly with your IAM credentials, and see if the error disappears. Once resolved, you can re‑enable SSO.
• Give it time. In many cases the status clears on its own after a short wait (usually under 10 minutes). If you’ve verified email and permissions, simply pause and refresh the page later.

If after walking through the list the banner is still there, move on to the more technical troubleshooting steps.

Use the AWS CLI to probe CloudShell status

Open a terminal on your local machine and run:

aws cloudshell get-environment --region us-east-1

If the response contains "status": "READY", the backend is healthy and the problem is likely client‑side (browser cache, SSO token, etc.). If you see "status": "VERIFICATION_IN_PROGRESS" for more than 15 minutes, it’s time to contact support.

Inspect CloudTrail for related events

CloudTrail logs can reveal whether a verification request was triggered and whether any errors were recorded. Look for events with the source cloudshell.amazonaws.com and the event name StartEnvironment. Any “AccessDenied” or “Throttling” messages point to missing permissions or service limits.

How to prevent the error from resurfacing

Most of the friction disappears once your account is fully set up, but a few proactive steps can keep CloudShell humming smoothly:

• Make sure the root email is verified as part of the initial account onboarding.
• Attach AWSCloudShellFullAccess to every IAM role that needs CloudShell, rather than adding it ad‑hoc later.
• Document the region you intend to use for CloudShell in your team’s runbooks – avoid launching the service in a region still in preview.
• Schedule a quarterly review of IAM policies to catch accidental removals that could re‑trigger verification.

When to reach out to AWS Support

If you’ve confirmed email ownership, attached the correct policy, switched to a supported region, cleared your browser, and still see the verification banner after 30 minutes, it’s likely a backend issue. Open a support case under the “Technical” category, reference the CloudShell environment ID (found via the CLI command above), and attach any relevant CloudTrail logs. AWS engineers can then verify whether an internal service dependency is holding up the verification process.

FAQ

Is the “Account Verification In Progress” error permanent?

No. It is designed to be temporary. In most cases it resolves automatically once AWS confirms your email and IAM permissions.

Can I use CloudShell without the AWSCloudShellFullAccess policy?

Technically you can grant a custom policy with the same permissions, but the managed policy is the simplest and most reliable way to avoid verification roadblocks.

Why does the error appear after I enable AWS SSO?

SSO token propagation can take a few minutes. During that window CloudShell may still see the underlying IAM identity as unverified, triggering the status banner.

Do I need to wait for the verification each time I open CloudShell?

Only the first time after a major account change. Once the environment is marked “READY,” subsequent launches should be instantaneous.
