I stored a username and password for a host, but when connecting I get sometimes asked for the password
Does the latest update fix the issue? If not please try to create an identity in the Keychain with your username and password. And then attach this identity to your host. This should help.
The next version definitely will work fine.
I’m seeing the same issue, with the update as of February 3, 2018. I can’t save ssh login nor password for any existing profiles
