If you're seeing this problem, then the system to which you're
connecting is insecurely configured and using obsolete cryptography.
You should inform the maintainers of that system of that fact and ask
them to fix it.

You should run "ssh -vvv SERVER", where SERVER is the server to which
you're connecting (e.g., git@github.com or whatever) and see what the
output prints.  That should tell you why it's falling back to a
password-based configuration.

Note that credential managers are only used for HTTP and HTTPS
credentials and not for SSH, which is separate.
