Password Complexity Rules

By default Zotonic only enforces that your password is not blank. However, if you, your clients or your business require the enforcement of Password Complexity Rules Zotonic provides it.

Configuring Password Rules

After logging into the administration interface of your site, go to the Config section and click Make a new config setting. In the dialog box, enter mod_admin_identity for Module, password_regex for Key and your password rule regular expression for Value.

  • must have at least one upper-case letter (?=.*[A-Z])
  • must have at least one special character (?=.*[@#$%^&+=])

Putting those rules all together gives the following password_regex:
