Note: Please Disconnect the webdav connection when you finish your work, as the webdav session expires after eight hours.
(Leaving a webdav connection open poses a security risk.)
After that time is up, if you have NOT disconnected, you will be prompted to re-authorize via 2FA, repeatedly, until you respond.
If you do not respond, your duo account will get locked.
A possible other option is to use the 24-hour-valid “JWT”. To get one go here
