improve keyboard-interactive multi-steps

[xiaosunzhu]

I have encountered a very inconvenient situation about keyboard-interactive.

1. open session, enter username, prompt "YubiKey ....." on keyboard-interactive pop-up
2. input yubikey, and next, according to the rule, need input account password, but nothing is responding on keyboard-interactive pop-up
3. delete key in the input box manually, then input password and next, authetication success

Another little suggestion: why not save username for session?

Sorry for the late reply. Recently I have been focusing on developing WindTerm_2.4.0_Prerelease_2.

I don't know why the server will reply ssh_packet_userauth_info_request: **0** keyboard-interactive prompts, have you tried any other SSH clients and how do they handle this?

If you only want to save the username for your sessions, please set the host of the session to user@host, e.g. root@127.0.0.1.

[xiaosunzhu]

Thank you for the advice. user@host could store username indeed, but still need to confirm in popup.

There are 2 keyboard-interactive steps. Other ssh client is normal to process it, just pop up interactive twice.

Another one could improve:
I choose 'Attempt keyboard-interactive authentication' only, but 'Login' dialog default tab still 'Password', very inconvenient.

I am happy to inform you that WindTerm_2.4.1 has been released and both of your proposals have been implemented. Please download and check it, thank you.

[xiaosunzhu]

Wow, thanks for the improvement.

I tried 2.4.1, the second issue have been fixed, great!
But the first one, keyboard-interactive multi-steps, still not show tip and clean input for next step, still need clean input manually.
