Pick a length, choose character types, and generate a cryptographically strong password instantly.
How to use the Password Generator
- Choose your Password Length — 16 is a good default, 20+ for important accounts.
- Tick the character types to include — uppercase, lowercase, numbers, symbols.
- Press Generate Password — strength and entropy are shown with the result.
What makes a password strong
Length beats cleverness. Every extra character multiplies the guesses an attacker needs — a 16-character random password is stronger than any clever 8-character arrangement.
This generator uses the browser's cryptographic random source (crypto.getRandomValues) and deliberately excludes lookalike characters — 0/O, 1/l/I — so passwords stay readable when you type them.
The entropy number shown with each password tells you its real strength: below 40 bits is weak, 60+ is strong, 90+ is very strong.
How to actually stay safe
Never reuse passwords. One leaked site should not unlock your email and your bank. A password manager makes fifty unique passwords effortless.
Turn on two-factor authentication everywhere it matters — email and banking first. A strong password plus 2FA stops almost all account takeovers.
Never share passwords over chat or email; real services never ask for them.
Frequently asked questions
How long should my password be?
At least 12 characters; 16 or more for email, banking and password-manager master passwords. Length matters more than special symbols.
Is this password generator safe to use?
Yes — passwords are generated locally in your browser using a cryptographic random source. Nothing is sent, logged or stored anywhere.
Can anyone see the passwords I generate?
No. There is no server involved — the password exists only in your browser tab until you close or regenerate it.
Why does it skip 0, 1, O, l and I?
Those characters look alike in many fonts (zero vs O, one vs l/I). Removing them keeps passwords readable without meaningfully reducing strength.
Should I use the same password everywhere?
Never. Reuse means one breach unlocks everything. Use unique passwords plus two-factor authentication on important accounts.
