This web page allows you to create a Dropbox token to be used with Duplicacy.
When you're ready to proceed, please click on "Connect" below. It will take you to the Dropbox website and ask you to log in to Dropbox and grant Duplicacy the permission to back up files to your Dropbox folder.
You will then receive a token which can be supplied to Duplicacy when prompted. This web page never logs or saves any information, or in anyway interacts with Dropbox on your behalf beyond providing you with a token and refreshing that token for you.
