Password Generator

Password Length16

Strong Password Generator

The Password Generator creates cryptographically secure random passwords using your browser built-in crypto.getRandomValues() API — the same randomness source used by professional security tools. Set a length from 8 to 64 characters, then select which character sets to include: lowercase letters (a–z), uppercase letters (A–Z), digits (0–9), and special symbols (!@#$%^&*). The generated password appears instantly with a real-time strength meter rating it as Weak, Fair, Strong, or Very Strong.

Password security directly determines your protection against credential stuffing, brute-force attacks, and account takeovers. A 12-character password using all character types has approximately 475 trillion possible combinations — cracking it would take centuries at current computing speeds. A 16-character password extends that to quintillions. The single most dangerous password habit is reuse: one breached site exposes every other account using the same password. Creating a unique, strong password for every account is the most effective personal security measure available.

Best practice is to pair this generator with a password manager — 1Password, Bitwarden, or your browser built-in manager — which stores passwords encrypted and autofills them. You only need to remember one strong master password. Never store passwords in plain-text notes, spreadsheets, or emails. Never share passwords over unencrypted channels. All generation in this tool happens locally in your browser — no passwords are ever transmitted, stored, or logged anywhere.

Frequently Asked Questions

How do I create a strong password?
Use at least 12 characters and include uppercase letters, lowercase letters, numbers, and symbols. Avoid dictionary words, names, and predictable patterns like 123 or abc. Our generator handles all of this automatically.
What makes a password secure?
Security comes from length and randomness. A 16-character random password is far stronger than a 30-character predictable phrase. Using all four character types (upper, lower, digits, symbols) maximizes the number of possible combinations an attacker must guess.
Is my generated password stored anywhere?
No. All password generation happens entirely in your browser using the crypto.getRandomValues() API. No password is ever sent to a server, stored in a database, or logged anywhere.
How long should my password be?
For most accounts, 16 characters provides excellent security. For high-value accounts such as banking, email, or your password manager master password, use 20 or more characters. The generator supports up to 64 characters.
What special symbols are included?
The special symbols set includes common symbols accepted by most websites: !@#$%^&*()-_=+[]{}|;:,./<>? If a site rejects certain symbols, uncheck that option and regenerate — a longer all-alphanumeric password is still very strong.
Should I use a password manager with generated passwords?
Yes. Password managers like Bitwarden (free and open-source), 1Password, or your browser built-in manager store passwords encrypted and autofill them. This lets you use a unique strong password for every site without memorizing them.
Is this password generator truly random?
Yes. It uses crypto.getRandomValues(), which is the browser cryptographically secure pseudorandom number generator (CSPRNG). This is not predictable or reproducible, unlike Math.random().
