A Node.js CLI app to obtain Twitter credentials in "out of band" mode
If you ever want to write an application that connects to Twitter but you don't want to provide everything needed for a full-scale OAuth process like callback URLs and such. (And if you want to register your app on account A but use it with account B)
For cases like these Twitter has a nice feature called "out of band" or obb authentication. Using your apps consumer key and consumer secret you can generate a request token that can be passed to Twitter as an URL-parameter.
Instead of performing a callback to your backend you will receive a PIN-code for verification. A PIN-code that can then be used to obtail the final access token and access token secret
npm install twitter-oob -g
