Secure Password Generator — Cryptographically Random

⚡ Quick answer: Password Generator: Generate cryptographically secure passwords with a strength meter and crack-time estimate. It runs 100% in your browser — nothing is uploaded, no account needed.

What actually makes a password strong

Length beats cleverness. A random 16-character string from a full character set has so much entropy that offline cracking is infeasible, while "correct-horse-battery-staple" with one digit added feels safer but is not. The generator draws from a cryptographically secure random source in your browser (the same API your bank's site uses), optionally excluding ambiguous characters like 0/O and 1/l/I if the password will ever be read aloud or transcribed.

How to use the output responsibly

Generate, copy, paste into your password manager, and close the tab — do not screenshot it, do not email it to yourself, and do not store it in a notes app. A password manager is the only sink that keeps a strong password usable; a password written down somewhere is a weak password with extra steps. Reuse is the real danger: the generator exists precisely so you can afford a unique password for every site, which means a breach of one service stops at that service.

Who uses this

Anyone setting up a new account, rotating Wi-Fi or admin credentials, or auditing an old password that has served three years too long. Nothing is logged, nothing is stored, and the random source is the operating system's own — the generator could not report your password even if it wanted to.

How to generate a secure password (3 steps)

1. Set the length — 16 is a good default, 20+ is stronger still. Longer is almost always better than more symbol types.
2. Toggle the character sets (upper, lower, numbers, symbols) to match whatever the site requires, then hit generate.
3. Check the strength meter — it shows an actual crack-time estimate, which is the number that explains why length wins. Then copy it once and store it in your password manager.

FAQ

• Is it really random? Yes — it uses crypto.getRandomValues(), the same cryptographic API banks and TLS use, not Math.random().
• Should I reuse passwords? No — use a unique password per site and keep them in a password manager. The crack-time estimate shows why two 8-character passwords are a bad plan.
• Is the password sent to a server? No. It is generated on your device and never leaves the browser, even briefly.
