Laravel password validation rule

by

I have had a similar scenario in Laravel and solved it in the following way.

The password contains characters from at least three of the following five categories:

  • English uppercase characters (A – Z)
  • English lowercase characters (a – z)
  • Base 10 digits (0 – 9)
  • Non-alphanumeric (For example: !, $, #, or %)
  • Unicode characters

First, we need to create a regular expression and validate it.

Your regular expression would look like this:

^.*(?=.{3,})(?=.*[a-zA-Z])(?=.*[0-9])(?=.*[\d\x])(?=.*[!$#%]).*$

I have tested and validated it on this site. Yet, perform your own in your own manner and adjust accordingly. This is only an example of regex, you can manipulate the way you want.

So your final Laravel regex rule should be like this:

'password' => [
    'required',
    'min:6',
    'regex:/^.*(?=.{3,})(?=.*[a-zA-Z])(?=.*[0-9])(?=.*[\d\x])(?=.*[!$#%]).*$/',
    'confirmed'
]

Note:

  1. I have tested and validated it on both the regular expression site and a Laravel 5 test environment, and it works.
  2. I have used min:6, this is optional, but it is always a good practice to have a security policy that reflects different aspects, one of which is minimum password length.
  3. I suggest you to use password confirmed to ensure user typing correct password.
  4. Within the 6 characters, our regex should contain at least 3 of a-z or A-Z and number and special character.
  5. Always test your code in a test environment before moving to production.
  6. What I have done in this answer is just example of regex password

Regarding your custom validation message for the regex rule in Laravel, here are a few links to look at:
