How to login using SSH key?

[anta40]

I login to my development VPS using SSH key.
This is how I setup my connection:

Protocol: SCP
Remote host: xxx.xxx.xxx.xxx
Port number: 22
Username: anta40
Password: ....

OK, I'm supposed to use the correct SSH key, not the password. How to do it? On other SCP clients, I can easily pick it.
By pressing Ctrl+C (to show the configuration parameters), this is what I see under "SSH configuration path": ~/.ssh/config (which is correct). And anta40 is the same username in ~/.ssh/config.

termscp always gives me this:
authentication failed ([Session(18)] Authentication failed (username/password))

Perhaps I miss something?
I'm on macOS, btw.

The ssh configuration file should work, if it doesn't there's something wrong with it or it has patterns that are not supported by the library.

Anyway, there is built-in storage which always works.

Ah I see. For me, the UI is a bit un-intuitive that you have to open another menu to provide the SSH key (on other SCP clients, when you are setting up a new connection, usually the SSH key field is located under the password).
Got it, anyway.
