SUMMARY My server have a three-layer SSH protection: SSH key, password, and TOTP. While Dolphin can pass the first one, the rest (keyboard interrupts) cannot be done, and Dolphin just says "failed". STEPS TO REPRODUCE 1. Set up a SSH server with similar setup (I use google-authenticator as the keyboard interrupt, but you can use any) 2. Try to SSH into it via terminal (you can) 3. Try to sftp into it via Dolphin (you cannot) OBSERVED RESULT Failed. (That's what it excaly said.) EXPECTED RESULT Keyboard interrupt should redirect to input boxes, and it should pass once I entered all valid informations.
