SSH issue

hi all
I have VPS server running Linux OS and from time to time I need to connect to my server through SSH service and I’m using putty.
Now when I connect to the server and after I write my password it’s asking me about the security key.

What I need it’s two things:

1-How to provide the security key?
2-Is there any way to disable the security key in the next time I need to access the SSH using root username and password only without any other requirement.

 

hi infopro
what I need now the way to disable the security code I need to access the SSH using root username and password only.

I try to disable it from SSH Password Authorization but when I try to connect to the server it's give me the following error:

PuTTY Fatal Error
disconnected: no supported authentication methods available.
may you please help me.

 

ok now I disable SSH Password Authorization Tweak
but there was I note in your link (Remember: If passwords are disabled, your users must use SSH keys. ) is there any way to disable this feature also I don't want use SSH Keys (privet or public).

I remember that I am able to connect to another server without SSH key or SSH Password Authorization Tweak and I need to know the steps to do that.

 

any update please.
