The ssh terminal central widget works with username/password and also the native ssh agent for Linux/Mac and the Putty pageant agent for Windows.
It also supports 2FA ssh logins protected by Duo and will offer interactive prompt to choose how to send the 2FA auth or enter OTP code.
It is a multi-tabbed terminal so clicking to the right of the existing tab will spawn a new tab just like it does in a browser(Premium Feature). For more information about how that works see the PyPi link here. This portion of the app is opensource and suggestions and code tweaks are welcome on our gitlab here.
