Upcoming change to Duo Unix authentication (Oct 25)

Just received an email from our Duo admins regarding the Oct 25 update for unix authentication. Right now our development server is setup where doing su to another account doesn’t prompt for a duo approval (it only prompts for SSH at the time of connection). We want it to keep this way. If we don’t install the upcoming update on Duo, our system won’t be impacted right?


Correct, if you do not update your Duo Unix install to the newer version you will experience no change.

If you install from packages you may need to ensure that the package install update does not happen automatically.

Keep in mind that future changes to our service or to the Duo Unix application may prevent older versions from working. We send end-of-life notifications to affected customers in accordance with our End of Sale, Last Date of Support, and End of Life Policy.
