Managing access permissions effectively is an important aspect of maintaining a secure and collaborative environment in Amazon Quick. Quick supports versatile user management options designed to accommodate various identity types and organizational needs. You can provision users natively through Quick Identity or manage them through enterprise identity providers such as AWS IAM Identity Center or Active Directory. These systems allow user roles including Admin, Author, and Reader to be assigned and grouped according to job functions and security requirements. As team members join, change roles, or leave the organization, administrators must make sure transitions happen smoothly without disrupting business workflows or creating security gaps. Regular access reviews are important for maintaining security in your Quick environment. Plan monthly or quarterly audits of user roles to confirm everyone has appropriate permissions. When team members’ responsibilities change, proactively transfer ownership of their dashboards and analyses to prevent orphaned resources. This practice, recommended in the AWS Well-Architected Framework, helps maintain continuity for business-critical visualizations. In this post, we focus on one specific but important user lifecycle task: downgrading user roles. Why downgrade? The principle of least privilege applies strongly to Quick administration. Users should have access only to what they need for their specific job functions. Downgrading user roles is a key part of enforcing least privilege. When a user’s responsibilities no longer require authoring or administrative capabilities, reduce their role accordingly to minimize the security surface area. Quick pricing is also role-based: Authors and Admins pay a fixed monthly per-user fee, while Readers use session-based pricing. Organizations with users provisioned as Authors who only consume dashboards can reduce costs substantially by right-sizing them to Reader roles. For current pricing details, see the Amazon Quick pricing page. For more granular control beyond the built-in roles in Amazon Quick, consider complementing role assignments with Custom Permissions, which restrict specific capabilities within a role tier. The integration of Amazon Quick with AWS Identity and Access Management (IAM) provides additional permission boundaries that complement the basic role system. Scope of this post Although the exact steps depend on the user identity type, this post primarily addresses Amazon Quick Identity users (also called Quick-managed users). Users authenticated through IAM Identity Center or Active Directory typically have role changes managed through their external identity provider group mappings. If your environment uses IAM Identity Center, role downgrade is handled by moving the user from one IdC group to another (for example, from a Quick-Admins group to a Quick-Readers group). No step-down sequence is required. Although the Amazon Quick console doesn’t provide a direct downgrade path for all role transitions (specifically, you cannot downgrade from Admin to Reader or from Author to Reader directly through the console interface), two reliable solutions exist: a manual deletion-and-recreation method, and an approach that uses the AWS Command Line Interface (AWS CLI). We walk you through both techniques to help you maintain proper access management as your team evolves. Prerequisites Before we begin, make sure you have an active AWS account with administrator access to Amazon Quick. If you plan to use the CLI method, you need the AWS CLI installed and configured on your machine. It’s also helpful to prepare a list of users whose roles need changing. Understanding Amazon Quick roles Amazon Quick offers two subscription tiers with distinct role sets: Subscription Roles Capabilities Amazon Quick Enterprise Admin Pro, Author Pro, Reader Pro Full BI + AI features (agents, topics, Q&A, stories, generative summaries) Amazon Quick Sight (BI-only) Admin, Author, Reader Traditional BI authoring and consumption The console does not provide a direct way to downgrade from any Author tier to any Reader tier. The update-user API enforces this same constraint, rejecting direct downgrades with a “You cannot downgrade a user role” error. The following screenshot shows the Amazon Quick Suite user management page, where the console offers no direct control to move a user from an Author tier down to a Reader tier. This illustrates why the methods in this post are necessary. Figure 1: Amazon Quick Suite user management page The CLI step-down method works reliably for the legacy BI-only roles (Admin, Author, Reader), following this sequence: Admin > Author > Restricted Reader > Reader This same sequence also works for Pro users, as long as the intermediate steps use the legacy roles. For example, Author Pro > Author > Restricted Reader > Reader Pro completes successfully. Important considerations before making changes When implementing role changes through either method, there are several important factors to keep in mind. First, verify that all users in your list are currently Admin or Author users before making changes. Attempting to downgrade users who already have lower permissions might cause errors. Resource ownership questions still apply even when using the CLI method. Users being downgraded will no longer be able to edit resources they previously owned. For larger organizations using the CLI method, consider loading user email addresses from a CSV file rather than hardcoding them. If you use AWS CloudShell instead of a local CLI installation, you can omit the AWS Region specification because AWS CloudShell automatically uses your current console Region context. Transferring asset ownership (do this first) Before deleting a user, it’s essential to make sure that any assets they own, such as dashboards, datasets, and analyses, are properly reassigned. This prevents disruptions and avoids leaving resources orphaned. If the user is an Author, verify whether they own any datasets or dashboards, and follow the same asset reassignment steps described here. There are three main ways to handle asset ownership transfers in Amazon Quick. Option 1: Proactively transfer ownership to another admin The most controlled approach is to manually reassign ownership before deleting the user. To do this, go into each asset in Quick, choose Share, and assign another admin as a co-owner. With this method, you can determine exactly who takes over each resource, which is especially useful for high-impact dashboards or datasets. Although this can be time-consuming in large environments, it gives you the flexibility to distribute assets according to your team’s structure and responsibilities. The following screenshot shows the Share dialog for an asset, where you add another admin as a co-owner so that ownership is transferred before the original user is removed. Figure 2: Transferring asset ownership to another user Option 2: Use the Amazon Quick bulk asset transfer on the Admin page If the user owns many assets, the manual method can become inefficient. In this case, you can use the Manage assets feature available in the Admin section of Quick. With this tool, administrators can perform bulk ownership transfers or update sharing permissions for multiple assets at once. It streamlines the reassignment process significantly, particularly when offboarding users or managing organizational changes. For more details on how to use this feature, see the official Managing assets in Amazon Quick documentation. Option 3: Share assets with a Quick user group Another effective strategy is to share assets with a user group. For Quick Identity users, you can create a Quick group, add relevant team members, and share dashboards or datasets with the group rather than individual users. If your account is integrated with IAM Identity Center or Active Directory, equivalent groups are created and managed in those systems, and Quick uses those external groups for access control instead of Quick-managed groups. This way, access to shared resources remains intact even if a specific user is deleted. It’s a resilient approach that reduces the need for reassigning ownership in the future and helps maintain consistent access across dynamic teams. Manual method: Deleting and recreating the user Although not the most efficient approach, the manual deletion and recreation method is one option for environments where CLI usage isn’t feasible. This method involves removing the admin user entirely and then recreating them with reader permissions. This same manual method also applies when downgrading an Author to a Reader, though typically with fewer complications around asset ownership. Because this method requires deleting the user account before recreating it with a lower role, careful preparation is essential to avoid losing valuable resources and disrupting workflows. Make sure you have completed the asset ownership transfer described in the previous section before proceeding. Step 1: Delete the admin user After you transfer ownership of all resources, sign in to the AWS Management Console and navigate to the Amazon Quick service. From there, choose your profile icon, and then choose Manage Quick, followed by Manage users. When you locate the admin user you want to downgrade, choose the delete icon next to their name and confirm the deletion when prompted. This completely removes their current access to the system. If you haven’t transferred all resources beforehand, Quick presents an ownership transfer dialog. This dialog prompts you to select another admin who will receive ownership of all the user’s resources. Select an appropriate admin from the list, then confirm the transfer by choosing Delete and transfer. This built-in transfer mechanism helps prevent orphaned resources but transfers everything to a single admin. For more granular control, use the proactive approach mentioned earlier to distribute resources strategically among different team members. If you skipped the proactive transfer, the deletion dialog shown in the following figure lets you reassign all of the user’s resources to a single admin before the account is removed. Figure 3: Built-in resource transfer during user deletion Step 2: Recreate the user with the Reader role After successfully deleting the user, remain on the Users page and choose Invite users. Enter the user’s email address and select the Reader role from the available options. Send the invitation to allow the user to rejoin Quick with their new, more restricted permissions. Step 3: Verify the role change After the user accepts the invitation: Confirm that their permissions have been updated to Reader. Verify that they can only view dashboards and reports. Confirm that they can’t modify or create content. CLI method: Step-down role transition (recommended) If you prefer to use the AWS CLI or AWS CloudShell, you can programmatically change the user’s role. Because Quick requires role changes to be made in a specific sequence, you can’t transition directly from any Admin to any Reader. Instead, you must step through intermediate roles. Important notes Replace with your AWS account ID. Replace with the username of the user. Replace with the user’s email address. If you’re using the AWS CLI outside CloudShell, specify the --region parameter. The --role value must match the API role name exactly (see the preceding table). Example: Legacy track (Admin to Reader) Step 1: Change role from Admin to Author: aws quicksight update-user \ --aws-account-id \ --user-name \ --namespace default \ --email \ --role AUTHOR Step 2: Update role from Author to Restricted Reader: aws quicksight update-user \ --aws-account-id \ --user-name \ --namespace default \ --email \ --role RESTRICTED_READER Step 3: Change role from Restricted Reader to Reader: aws qu [truncated for AI cost control]
