Introduction to Javascript Password Validation

Password validation in JavaScript is typically required in web applications for client-side validation. JavaScript regex can be used to enforce password policies, such as requiring a mix of character types and a minimum length. An example regex pattern is /^(?=.*[a-z])(?=.*[A-Z])(?=.*\\d)(?=.*[@$!%*?&])[A-Za-z\\d@$!%*?&]{8,}$/.

What is JS Password Regex?

The regex pattern for password validation in JavaScript includes checks for diverse character types and length.

The Password Regex Pattern

  • Pattern:

    /^(?=.*[a-z])(?=.*[A-Z])(?=.*\\d)(?=.*[@$!%*?&])[A-Za-z\\d@$!%*?&]{8,}$/

    This pattern mandates mixed characters and a minimum length of 8.

How to Validate Passwords in JavaScript?

To validate passwords in JavaScript:

function isValidPassword(password) {
    const regex = /^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[@$!%*?&])[A-Za-z\d@$!%*?&]{8,}$/;
    return regex.test(password);
}

console.log(isValidPassword("Example123!")); // true or false

Uses of Password Regex Validation

  1. Client-Side Security: Enforcing strong passwords in user forms before submission to the server.

  2. Usability: Providing immediate feedback to users on password strength and requirements.
