+Connect to S3 authenticating with AWS IAM Identity Center
+====
+
+> [AWS IAM Identity Center](https://docs.aws.amazon.com/singlesignon/) (successor to AWS Single Sign-On) centrally
+> manages access to multiple AWS accounts. It enables users
+> to sign in once using their existing corporate credentials (such as Okta or Microsoft Entra ID) to access authorized
+> resources like S3 via short-lived credentials.
+> Use AWS IAM Identity Center to authenticate with S3 by configuring as an OpenID Connect (OIDC) Identity Provider in
+> AWS IAM.
+
+The [AWS IAM Identity Center OpenID Connect (OIDC) web service](https://docs.aws.amazon.com/singlesignon/latest/OIDCAPIReference/Welcome.html)
+is used to
+authenticate users with AWS IAM Identity Center.
+
+:::{admonition} Requirements
+:class: warning
+
+* Cyberduck [9.5.0](https://cyberduck.io/changelog/) or later required
+* Mountain Duck [5.3.0](https://mountainduck.io/changelog/) or later required
+  :::
+
+## Configuration in AWS IAM Identity Center
+
+In [AWS IAM Identity Center Console](https://console.aws.amazon.com/singlesignon) choose to *Enable IAM Identity Center*
+in a dedicated region.
+
+1. Follow the
+   documentation [Getting started with IAM Identity Center](https://docs.aws.amazon.com/singlesignon/latest/userguide/getting-started.html).
+   Optionally
+   customize [AWS access portal](https://docs.aws.amazon.com/singlesignon/latest/userguide/configure-the-access-portal.html)
+   URL in _Settings → Identity source → Actions → Customize AWS access portal_ and configure a custom external identity
+   provider (IdP) to manage users and groups by following the
+   [documentation](https://docs.aws.amazon.com/singlesignon/latest/userguide/tutorials.html) such
+   as [Microsoft Entra ID](https://learn.microsoft.com/en-us/entra/identity/saas-apps/aws-single-sign-on-tutorial).
+
+2. Copy the following values or alternatively setup your configuration
+   with AWS CLI:
+
+   :::{admonition} Required Configuration Values
+   :class: note
+    - _Account ID_ identifying your AWS account from the top right corner of the AWS console.
+    - _Region_ from _Dashboard → Settings summary → Region_
+    - SSO start URL from _Dashboard → Settings summary → Issuer URL_ or _AWS access portal URL → Dual-stack_.
+      :::
+
+   :::{tip}
+   Users can copy the _SSO start URL_ from the _AWS access portal_ page at _Accounts → Access keys → AWS IAM Identity
+   Center credentials (Recommended)_.
+   :::
+
+3. Create a permission set to limit access for users to S3 in _Permission sets → Create permission set_.
+    - Choose _Custom permission set_ in _Select permission set type_ and select _Next_.
+    - Expand _AWS managed policies_ and select _AmazonS3FullAccess_ or _AmazonS3ReadOnlyAccess_ and optionally
+      _CloudFrontFullAccess_ managed policies and select _Next_.
+    - Name the permission set and select _Next_.
+    - Select _Create_ and copy the _Permission set name_ from _General settings_.
+
+## Setup Users and Groups
+
+:::{tip}
+Alternatively attach a custom identity source in _Settings → Identity source_. You will manage all users and groups in
+an external identity provider (IdP).
+:::
+
+1. Choose _Users → Add user_ and create a user with a password.
+2. The user must login to the AWS access portal URL `awsapps.com/start` with the username and one-time password.
+3. Assign a AWS account to the user in _Users → Username → AWS accounts → Assign accounts_.
+4. Select the _AWS Organization_ and assign the [previously created](#configuration-in-aws-iam-identity-center)
+   _Permission Set_ and
+   select _Assign_.
+
+## Create a bookmark in Cyberduck or Mountain Duck
+
+1. Add a new [Bookmark](../cyberduck/bookmarks.md) in Cyberduck or Mountain Duck and choose *AWS S3 (IAM Identity
+   Center)* in the protocol dropdown.
+2. Choose _Connect_ and select the AWS CLI profile name when prompted.

+   :width: 400px
+   :::
+
+   :::{tip}
+   Choose _Cancel_ to skip configuration from the AWS CLI profile and continue with manual configuration.
+   :::
+
+   :::{admonition} Using AWS CLI Configuration
+   :class: tip
+   Pre-configure the settings using AWS CLI to allow reading configuration options from the `~/aws/config`
+   file including the _Issuer URL_.
+
+    1. Obtain your IAM Identity Center [configuration](#configuration-in-aws-iam-identity-center) information.
+    2. Install the [AWS CLI](https://docs.aws.amazon.com/cli/latest/userguide/getting-started-install.html)
+    3. Configure your profile with the `aws configure sso` wizard using the command line:
+
+       ```
+       $ aws configure sso
+       SSO session name (Recommended): my-sso
+       SSO start URL [None]: https://my-sso-portal.awsapps.com/start
+       SSO region [None]: us-east-1
+       SSO registration scopes [None]: sso:account:access
+       ```
+
+       :::
+
+3. Choose the _SSO Region_ when prompted.
+
+   :::{warning}
+   Must match the region selected when [setting up](#configuration-in-aws-iam-identity-center) IAM Identity Center in
+   AWS.
+   :::
+
+   :::{image} _images/AWS_Region_Prompt.png
+   :alt: AWS Region Prompt

+   :::
+
+4. Enter the _Issuer URL_ or _AWS Access Portal URL_ when prompted for the SSO start URL.
+
+   :::{image} _images/AWS_Identity_Center_Issuer_URL_Prompt.png
+   :alt: AWS IAM Identity Center Issuer URL Prompt

+
+5. Login to AWS or your third-party identity provider followed by choosing _Allow access_ to _Cyberduck_ or _Mountain Duck_
+   in the AWS access portal.
+
+   :::{image} _images/IAM_IdentityCenter_Allow_Access.png
+   :alt: Web Browser Screenshot
+   :width: 800px
+   :::
+
+   :::{tip}
+   The web browser will prompt to open _Cyberduck_ or _Mountain Duck_ afterwards to continue
+   with the connection setup. You can close the web browser window after confirming access.
+   :::
+
+6. Choose the _AWS Account ID_ when prompted.
+
+   :::{tip}
+   This step is skipped if only a single AWS account is configured with your AWS IAM Identity Center instance.
+   :::
+
+7. Choose the _Permission set name_ when prompted previously [configured](#configuration-in-aws-iam-identity-center).
+
+   :::{tip}
+   This step is skipped if only a single AWS account is configured with your AWS IAM Identity Center instance.
+   :::
+
+:::{admonition} Troubleshooting
