Validating a password protection system Webcam software sex
In most browsers - those that support Java Script 1.5 (Firefox, Chrome, Safari, Opera 7 and Internet Explorer 8 and higher) - you can use more powerful regular expressions.
Very old browsers may not recognise these patterns.
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.
In any case browsers such as Firefox and Opera will enforce the HTML5 validation rules and present messages as shown here: Presumably the browser messages will change according to the users language - something that would never be possible using only Java Script.Consider the following: If you are using a supported browser you can use the form below to test the regular expression: If you want to restrict the password to ONLY letters and numbers (no spaces or other characters) then only a slight change is required.Instead of using is shorthand for 'any letter, number or the underscore character'.After all it's only the browser display being obfuscated and not the data transfer.Because the input type obscures the text typed, you should let the user confirm that they haven't made a mistake.
