Multiple Accounts

You can connect to multiple accounts at the same time. Create a new bookmark for every account and run through the OAuth flow. Make sure to log out in your browser prior to setting up a new bookmark to make sure the new bookmark is linked to a newly authenticated account.

Reset OAuth Tokens

If you have accidentally logged in with the wrong Dropbox Account or want to change the login of the Dropbox bookmark delete the current bookmark and create a new one to start a new authentication flow. Alternatively, you can reset the OAuth token by deleting the entries related to duck:dropbox?user=(user) out of the Windows Credential Manager or on macOS the entries related to api.dropboxapi.com out of Keychain Access.app.

Cyberduck CLI

You can list the root contents of your Dropbox with Cyberduck CLI using

duck --list dropbox:/

Refer to the Cyberduck CLI documentation for more operations. For subsequent invocations make sure to include the --username parameter and set it to the email address registered with Dropbox to allow the lookup of previously saved OAuth tokens.


Shared Folders

To do that, open your Dropbox Account within a web browser and navigate to the Shared section. Add the desired file or folder to your own drive by clicking on the Add button beside the file or folder.


A list of file versions can be viewed in the Versions tab of the Info window. Files can be reverted to a chosen version of this list.

Share & Request Files
