Prevent Cyberduck from prompting you for a Duo two-factor login on every file upload or download

If you connect to a remote host that requires two-factor authentication with Duo, Cyberduck will present you with a "Duo two-factor login" prompt for each file it uploads or downloads unless you make the following change to the default configuration:

  1. In Cyberduck, select Edit > Preferences > Transfers > General.
  2. Under "Transfers", use the "Transfer Files" drop-down to select Use browser connection.
Note:
As of October 14, 2018, two-factor authentication using Duo is required for access to the login nodes on Big Red II, Big Red II+, Carbonate, and Karst at Indiana University, and for SCP and SFTP file transfers to those systems. SSH public-key authentication remains an option for researchers who submit the "SSH public-key authentication to HPS systems" user agreement (log into HPC everywhere beta using your IU username and passphrase), in which you agree to set a passphrase on your private key when you generate your key pair. If you have questions about how two-factor authentication with Duo may impact your workflows, contact the UITS Research Applications and Deep Learning team. If you have system-specific questions, contact the UITS High Performance Systems (HPS) team. For help with Duo, see Get started with Two-Step Login (Duo) at IU and Help for Two-Step Login (Duo).
