We use Secure CRT 4.1 in Windows to connect to SLCs using ssh with the Password authentication method, but it does not work. An error message keeps reporting that the server (SLC) does not support Password authentication. There is no problem when connecting from the other hosts, e.g. Linux servers using OpenSSH. How can we resolve this?

SLCs do not support the less secure "Password" authentication, they require that you use "Keyboard Interactive"

In SecureCRT change the Primary authentication method from the default of "Password" to "Keyboard Interactive". Here is a screen shot from SecureCRT 5.1:

OpenSSH in Linux negotiates the authentication method with the SLC and uses Keyboard Interactive.

We believe that later versions of SecureCRT negotiate authentication, so you may be able to resolve this issue by upgrading to the latest version of SecureCRT.

Also, older versions of SecureCRT do not support the new ciphers and key exchange methods used in current SLC firmware. You may need to upgrade SecureCRT to get support for current ciphers and KEX.

As of this writing the current version of SecureCRT is 8.0, available from:

At this writing other Windows ssh clients that are known to work with SLCs are:
