WebDAV Login Issues

If the user account is configured with Require password change on next login, WebDAV login fails until the password is changed. Ask the user to sign in to the Files.com web interface and complete the password change before attempting WebDAV again.

When a user cannot log in over WebDAV, have them try the Files.com web interface. If the login fails there too, the problem is not specific to WebDAV.

Two-Factor Authentication

If 2FA is required, only certain methods work over WebDAV, and the user appends the code to their password. A user who has not signed in to the web interface since 2FA was required cannot authenticate over WebDAV at all until they complete setup there.

A person who needs both 2FA and desktop access is better served by the Desktop App, which answers the second factor once at login rather than forcing the factor into the password.
