Any higher processor supports HTTP authentication then MCF5223X series?. Like password auth, also change passwords, different user accounts like it comes in Embedded LINUX tiny web server. Looking in micro-controller like MCF5223x series only,
I'm not sure I understood the question.
Anyway, I have implemented a web server with HTTP Digest Authentication on a MCF5223x. HTTP Basic Authentication would be even easier to implement. User accounts would be trivial to do as well. So yes, it is possible.
