Though this solution may be simple, I'm sure this is one of those useful things that people will be Googling for and deserves its own entry on the site If only Google would be the first place to look :) Just look at the duplicates of this closed every some time.Any support for use of regex checks for e-mails I am 100% against.Because the input type obscures the text typed, you should let the user confirm that they haven't made a mistake.The simplest way to do this is to have the password entered twice, and then check that they are identical.To a regular expression, is a sequence of digits and punctuation characters, just like 2009-07-19.That makes it very hard to deal with higher-level concepts.A lot of websites now require registration, meaning that users need to be assigned a username and password.Here are some simple steps to make the process more secure.

The code presented below would then be used for letting the user change their password.The main stumbling block for many people is that there is nothing in the regular expression syntax that allows you to work with dates or numbers or email addresses or any other concept that most people would instantly recognize.Regular expressions only deal with characters, one at a time.With Regex Magic you can work directly with higher-level concepts such as dates, numbers, or email addresses.Using the integer pattern, you can tell Regex Magic to match a number between 1 and 12.
