I use Twitter primarily to send updates from websites to particular accounts. In other words, the Twitter account doesn't change.
I'm concerned that, with the phase-out of simple authentication, these systems will break - but OAuth seems like too much overhead for a connection that doesn't change. Is there a simple method that can be embedded in a script (e.g., into PHP) that will allow me to do this? Do I just need to authorize the account with the application once?
