Why Do You Need a Strong Password?

Passwords are the first line of defence protecting your online accounts from unauthorized access. Despite the rise of multi-factor authentication (MFA), passwords remain the primary credential for the vast majority of websites and apps. A weak, reused, or predictable password is one of the most common causes of account takeovers and data breaches.

According to the 2023 Verizon Data Breach Investigations Report, over 80% of hacking-related breaches involve compromised credentials. Generating a unique, random password for every account dramatically reduces your risk.

What Makes a Password Strong?

A strong password has several key properties:

• Length: The longer the password, the harder it is to crack. A 16-character password has astronomically more combinations than an 8-character one. Aim for at least 12–16 characters for standard accounts, and 20+ for critical accounts like banking and email.
• Randomness: Truly random passwords (generated by a cryptographic random number generator, as this tool uses) are far stronger than passwords based on words, names, dates, or keyboard patterns.
• Character variety: Mixing uppercase letters, lowercase letters, numbers, and symbols maximises the character set size, which multiplies the difficulty of a brute-force attack exponentially.
• Uniqueness: Using a different password for every site ensures that a breach at one service cannot compromise your other accounts.

How Is Password Strength Measured?

Password strength is commonly measured by entropy — the number of bits of randomness. Higher entropy = harder to crack. This tool classifies passwords as:

• Weak — fewer than 36 bits of entropy (typically short passwords with limited character sets).
• Fair — 36–59 bits (adequate for low-risk accounts; not recommended for anything important).
• Strong — 60–95 bits (suitable for most accounts).
• Very Strong — 96+ bits (recommended for high-value accounts like email, banking, and cloud storage).

Is This Password Generator Safe?

Yes. This tool uses the browser's built-in crypto.getRandomValues() API — the same cryptographic random number generator used by your operating system and security software. The password is generated entirely within your browser and is never transmitted to our servers. We cannot see, log, or store any password you generate here.

Password Security Best Practices

• Use a password manager: Tools like 1Password, Bitwarden, or Dashlane store all your unique passwords securely, so you only need to remember one master password.
• Never reuse passwords: If one site is breached, attackers will try your credentials everywhere else (credential stuffing attacks).
• Enable MFA: Even with a strong password, adding multi-factor authentication (via an authenticator app, not SMS) greatly increases your account security.
• Change passwords after breaches: Use haveibeenpwned.com to check if your email has appeared in known data breaches.
• Never share passwords: Not over email, SMS, or messaging apps. Use a password manager's secure sharing feature if you must share access.
• Avoid common patterns: Substitutions like "P@ssw0rd" or "pa$$word" are well known to attackers and offer no real protection over the plain word.
