Password Generator

Generate strong, random passwords with custom length and character settings.

Quick Answer

The Password Generator creates cryptographically random passwords with configurable length, uppercase, lowercase, numbers, and symbols. A live strength meter grades each result as it generates, and you can produce multiple passwords at once and copy them all in a single click.

What Is a Password Generator and Why Do You Need One?

Weak or reused passwords are the leading cause of account breaches. Our password generatorcreates cryptographically secure passwords using the browser's Web Crypto API — with full control over length (6–64 characters), character types, and complexity rules. All generation happens locally; nothing is ever sent to a server or stored anywhere.

How to Use the Password Generator

  1. Set the length — drag the slider. 16+ characters is recommended for email, banking, and social media accounts.
  2. Choose a password type — Random for maximum security, Memorable for passwords you type from memory, PIN for numeric codes.
  3. Enable character types — uppercase, lowercase, numbers, and symbols for maximum strength.
  4. Enable "Require each type" — guarantees at least one character from every enabled set.
  5. Click "New Password" — copy it directly into your password manager.

Where Can You Use Strong Passwords?

Personal Online Accounts

Email, social media, banking, and streaming — any account holding personal data needs a unique, strong password.

Work & Business

Corporate logins, SaaS tools, and VPNs. A compromised work account can affect an entire team, so strength here is critical.

App Development

Generate strong secrets for API keys, JWT signing secrets, database credentials, and environment variable values.

Shared & Verbal Access

Wi-Fi passwords, shared streaming accounts, or any credential you need to communicate aloud benefit from the Memorable or PIN modes.

Password Generation Modes Available

  • Random Characters — The most secure option. Combines uppercase, lowercase, numbers, and symbols into a fully random sequence. Ideal for accounts stored in a password manager.
  • Memorable — Combines common words with hyphens (e.g. eagle-river-stone-42). Great for passwords you occasionally need to type from memory.
  • Numeric PIN — Digit-only codes for ATMs, device locks, and simple numeric login systems. Increase length to 8+ for better security.
  • Pattern — Alternating consonant-vowel sequences (e.g. bevoral). Pronounceable, easier to type on mobile, and still randomly generated.

Understanding Password Strength and Best Practices

The entropy bar measures bits of randomness. More bits mean exponentially more possible combinations. Aim for 60+ bits for general accounts, 80+ bits for banking and email, and 100+ bitsfor master passwords. The "Time to Crack" estimate assumes 10 billion guesses per second — a realistic GPU brute-force rate.

Best practices: Use a unique password for every account — reuse is the single biggest security risk online. Store passwords in a manager (Bitwarden, 1Password, or iCloud Keychain). Enable two-factor authentication (2FA) wherever possible. Never share passwords via SMS or unencrypted email.

Frequently Asked Questions

Is this password generator cryptographically secure?+

Yes — all passwords are generated using the Web Crypto API, which provides true cryptographic randomness. No passwords are sent to any server or stored anywhere. All processing happens locally in your browser, making it completely private and secure.

What is password entropy and how many bits do I need?+

Entropy measures how unpredictable a password is in bits. A higher bit count means exponentially more possible combinations. For general accounts, aim for 60+ bits. For critical accounts like banking or email, use 80+ bits. A 16-character password with all character types typically exceeds 100 bits.

What is the difference between the four password types?+

Random Characters uses the full character set for maximum security — best for most accounts. Memorable combines real words for passwords you need to type regularly. Numeric PIN generates digit-only codes for ATMs and simple logins. Pattern alternates consonants and vowels for pronounceable yet random output.

Should I exclude similar characters like 0, O, l, and 1?+

Enable this option when passwords will be typed manually or read aloud to prevent confusion between visually similar characters. For passwords copied directly from a manager, keep all characters enabled for maximum entropy.

How often should I change my passwords?+

Modern security guidance from NIST recommends only changing passwords when there is evidence of a breach, not on a fixed schedule. Instead, focus on using a unique, strong password for every account and enabling two-factor authentication wherever possible.
