The latest versions of Cyberduck & Mountain Duck now allow to connect to S3 by authenticating with an OpenID Connect (OIDC) identity provider.
Connections to S3 with web identity federation use AWS Security Token Service (STS) API to obtain temporary security credentials to authenticate with S3.
With web identity federation, you don’t need to (…) manage your own user identities. Instead, users of your app can sign in using a well-known external OpenID Connect (OIDC)-compatible IdP. They can receive an authentication token, and then exchange that token for temporary security credentials in AWS that map to an IAM role with permissions to use the resources in your AWS account. Using an IdP helps you keep your AWS account secure, because you don’t users to have long-term security credentials.
Default connection profiles are provided to use Google or Azure AD as an identity provider in conjunction with AWS.
These default profiles will prompt users for the Role ARN configured in AWS IAM referencing the trust relationship configured with the identity provider. Assigned by AWS this has a format similar to arn:aws:iam::930717317329:role/my-role-name.
Assign a role. The role is crucial as it contains both the trust relationship with the identity provider and permission policy:
The trust policy restricts access to users authenticated with a specific identity provider and allows to filter for specific users in the Condition statement with access to the JSON Web Token (JWT) claims that can be matched.
Refer to the AWS documentation on Creating a role for web identity or OpenID Connect Federation.
The role that your application assumes must trust the identity provider that is associated with the identity token. In other words, the identity provider must be specified in the role’s trust policy. The call to
AssumeRoleWithWebIdentityshould include the ARN of the role that is specific to the provider through which the user signed in.
We have made available documentation to write your own connection profile for different combinations of S3/STS and identity provider such as MinIO S3 authenticating with MinIO STS and Keycloak (OIDC).
Refer to our S3 documentation.

SMB (Server Message Block) is used to access Windows File Shares or a Samba Linux Server. Cyberduck 8.7.0 adds support to access SMB shares as an light-weight, performant alternative to built-in support in macOS and Windows. Support in Mountain Duck is forthcoming in version 5.
To connect to your SMB (formerly known as CIFS (Common Internet File System) server such as a NAS (Network Attached Storage) using NTLM authentication, select SMB (Server Message Block) in Open Connection or the Bookmark configuration. The default domain name is set to “WORKGROUP” and can be changed to meet the username format requirement depending on the server setup.
You will provided with a list of available shares from the server or alternatively if not supported prompted to input the share name manually. Specify the share name as a Path in the bookmark to avoid connect to a single share.
Up-to-date information about SMB interoperability can be found in out documentation.

Dropbox recently adopted the File Provider API available on macOS to be used as the exclusive way to synchronize files with their own app. The most prominent change from a user perspective is the limitation to store all synchronized files in ~/Library/CloudStorage as required by the File Provider API. Many users with large data sets preferred to set a custom location on an external disk previously which is no longer an option.
Mountain Duck is a viable alternative to the official Dropbox client. It allows to connect to and synchronize your files in Dropbox without any additional bloat. In Mountain Duck Preferences, you can change your cache location to a different folder or even to an external drive.
Mounting your Dropbox in Finder is straight forward using Mountain Duck:
Once successfully connected, your files from Dropbox will open in Finder. To connect to a single folder instead of the root, add a path to your bookmark configuration. Without adding a Path to the bookmark configuration, you will be connected to the root of your Dropbox.
Connect to and work with multiple Dropbox accounts simultaneously. Repeat the above steps to connect to an additional Dropbox account you may have access. Open a new bookmark and login to the other Dropbox account in your web browser when authorizing access for Mountain Duck.
Alternatively, use Cyberduck to browse your Dropbox without syncing the files to your computer.

Boxcryptor has been acquired by Dropbox and will terminate free accounts as of January 31, 2023. Till then, all users have to look for an alternative. It is not clear how customers with existing contracts are served in the future and no new accounts are accepted. So why not use Mountain Duck with support for the Cryptomator vault format independent from a single provider?
Mountain Duck allows you to mount multiple cloud storages and servers as network drives on macOS and Windows using Smart Synchronization for offline access. Use the built-in, fully interoperable support for Cryptomator vaults to encrypt your sensitive data in password-protected vaults with end-to-end and zero-knowledge encryption. You do not need to have the Cryptomator apps installed but can access the same vault using Cryptomator for iOS for example.
Cryptomator is free and open-source software with no security by obscurity, no hidden backdoors from third parties, no need to trust anyone except yourself. No online services, no subscriptions, no accounts.
Follow these steps to migrate documents currently in Boxcryptor to a Cryptomator vault accessible through Mountain Duck:
Follow our documentation for step-by-step instructions to create a new vault or access an existing vault stored on your preferred cloud storage (including Dropbox).
