Duckdns doesn't require a password to login to Hassio

I am having trouble with using DuckDNS.

It seems to have installed correctly, I can open Hassio using the DuckDNS URL.

My problem is that it does not ask for a password to login.

My config has:
http:
# api_password: #!secret http_password
ssl_certificate: /ssl/fullchain.pem
ssl_key: /ssl/privkey.pem

If the hash symbol in front of the api_password it asks for my password, but does not except the password and will not connect to hassio.

Thanks for any help.

Never mind, I had a second # in front of the password, so when I removed the # at the beginning of the line the actual password from secret was still commented out.
