I agree that using a randomized token is better that using the default, but I think `$RANDOM` is too short and we would probably be better off leveraging `openssl` like we [do for Heroku](https://github.com/swanson/stringer/blob/master/README.md#installation).
```sh
echo "export SECRET_TOKEN=`openssl rand -hex 20`" >> $HOME/.bash_profile
```
