At work we hook into 3rd party applications for various things. One of these things is to handle our user authentication and login. Unfortunately, when this piece of the application doesn't work, development grinds to a halt until the other team can get that application back up and running. This can take hours which results in nothing getting done. If we can't log in, we can't verify the code we write.
This week I finished a feature that creates a bypass around this other application when a flag is enabled. It replaces the login screen and rewires all of the authentication code so we can access our own application and continue to verify our code as it is being developed. Hopefully this bypass won't be used much, but at least it is there so we can continue to work when we need it.
