Twitter API settings
You will need to register a Twitter Application to enable registration in Tweeria and parse user tweets. Open https://dev.twitter.com/ and create an application there.
There are two moments you need to pay attention:
Twitter must know the link redirect user to after the complete authorisation. There is Callback URL field in Twitter Application settings. Change it to domain url you're running Tweeria (local development IP for example)
You will need to generate API keys (consumer key and secret) for your application with Read/Write application access. Then copy these keys in your config file like this:
[parser]
auth.key = "211yXqgALGkB1B5xYbmBO5uQM"
auth.secret = "ivYvqD24zOyXEkEIOZvt3dvZlxjdD9GYmT6AQ99zhEFhF3zaW0"
parser.key = "211yXqgALGkB1B5xYbmBO5uQM"
parser.secret = "ivYvqD24zOyXEkEIOZvt3dvZlxjdD9GYmT6AQ99zhEFhF3zaW0"
Please note, user will have authorisation against the auth keys and parser will not parse user tweets if it has the different set of keys. Here is screen from Twitter:
