Is there anyway to use UE in a two-factor authentication environment?
Do you want to connect to an FTP/SFTP server using already a two-factor authentication environment?
As far as I know two-factor authentication is mainly required by a server to increase security because of users always saving user name and password and let the applications (browsers, FTP clients) automatically connect using the stored data. The applications do not support automatic answering on second authorization (most likely because not standardized) which increases the security. The same security can be reached if the user does not save user name and password and instead always enter it. But users often don't like that if there is the possibility to let the application pass this authentication information automatically.
UltraEdit supports standardized methods for authentication like user name, password, SSL certificate, public key and private key in nearly all combinations with or without storing the data according to what the user prefers.
