swaks auth fails, even with Application-Specific Passwords

Hello,
Since smtp servers were/are not fully working since yesterday and I started new development, I'm trying SMTP using swaks to track issues faster.
I generated an Application-Specific Password for swaks but it doesn't work:
[email]
[password]

Is App specific password working for smtp?
Ultimately, I need the other generated specific password to work for a local server I'm testing. It never worked so far (not sure if it's because of the smtp server issue or my server settings).
Thanks!
