Chris Hartjes has followed up on a previous post about user authentication in CakePHP with a few more comments in part two.

I got a question in the comments about my previous post on simple user registration about how to do some of the necessary validation for registration in the model. I thought I'd show some code I did to do exactly that.

He includes the code for his example with the key, he explains, being the use of a second field (the confirm password field) to do the validation.
