Password Generator — Cryptographically Secure, Browser-Based
Generate strong, cryptographically random passwords. Configurable length and character sets — runs in your browser.
Cách dùng
- 1 Set the length and how many passwords you need (1–100).
- 2 Pick which character sets to include — lowercase, uppercase, digits, symbols.
- 3 Toggle ambiguous characters (l, I, O, 0, 1) off if you'll be reading the password aloud or copying by hand.
Vì sao dùng công cụ này
- Cryptographically secure — uses the Web Crypto API (crypto.getRandomValues), not Math.random.
- Guarantees at least one character from each enabled set, then fills the rest from the combined alphabet.
- Entropy meter shows password strength in bits — 60+ is strong, 128+ is overkill.
- Generates 100 passwords in one click for bulk use.
- Never sends passwords to a server — pure browser-side generation.
Câu hỏi thường gặp
How long should my password be?
For high-value accounts, 16+ characters with all 4 sets enabled gives 96+ bits of entropy — currently uncrackable. For passphrases, longer is better.
What are "ambiguous characters"?
Visually similar pairs: l/I/1, O/0. Excluding them helps when you need to read or type the password by hand. Leave them in for systems where you'll paste the password.
Is "crypto.getRandomValues" really random?
It draws from the operating system's cryptographic random source — the same source used to generate TLS keys. It's the standard for security-sensitive randomness in browsers.
Do you log generated passwords?
No. The tool runs entirely in your browser. We see only that you visited the page (anonymous analytics, if enabled).
Password Generator là gì?
A Password Generator is a tool that produces random character strings suitable for use as login credentials. Secure generators draw entropy from a cryptographically strong random source (in browsers, the Web Crypto API's `crypto.getRandomValues`) rather than `Math.random`, and let the user mix uppercase, lowercase, digits, and symbols to satisfy site-specific complexity rules.
