How it works
Convert in three steps

Set your requirements

Choose password length (8–128 characters) and which character types to include: uppercase, lowercase, numbers, and symbols. Optionally exclude ambiguous characters (0, O, l, 1) for easier reading.

Generate

Click generate to produce a cryptographically random password. Regenerate as many times as you need.

Copy the password

One-click copy. The generated password is never shown elsewhere or stored — copy it immediately into your password manager.

FAQ
Common questions

Passwords are generated using the browser’s crypto.getRandomValues() API — a cryptographically secure random number generator. This is the same source of randomness used by security-critical applications and produces passwords with true entropy, not pseudo-random sequences.

For most accounts: 16–20 characters minimum. For high-value accounts (banking, email, primary accounts): 20–32 characters or more. Length is the biggest factor in password strength — a 20-character password with only lowercase letters is harder to brute-force than a 10-character password with all character types. Use a password manager to store generated passwords — you only need to remember one master password.

Ambiguous characters are visually similar pairs: 0 (zero) and O (capital O), l (lowercase L), 1 (one), and I (capital I). Excluding them makes passwords easier to type manually without errors. If you’re storing the password in a password manager and copying rather than typing, excluding them is unnecessary.

No. Password generation runs entirely in your browser using the Web Crypto API. Generated passwords are never transmitted, stored, or logged anywhere.

About the Password Generator

Weak and reused passwords are the most common cause of account compromise. A strong password is long, random, and unique to each account — which means it needs to be generated rather than invented. Human-chosen passwords follow predictable patterns even when people think they’re being creative. This generator uses the browser’s cryptographically secure random number generator to produce passwords with genuine entropy, not patterns. Configure the character set and length to match the account’s requirements, copy the result, and store it in a password manager.
