Secure Password Generator Online — Create Strong Random Passwords
Generate secure passwords
—Generate strong, cryptographically secure passwords instantly with our free online password generator. The tool runs on the Web Crypto API, using true random number generation (CSPRNG) for maximum protection. Configure password length from 8 to 64 characters, choose character types (lowercase, uppercase, digits, special symbols), exclude look-alike characters (1, l, I, O, 0), and batch-generate up to 100 unique passwords at once. A built-in Passphrase mode creates memorable yet highly secure phrases from a 240-word EFF-style wordlist. All computation happens locally in your browser, so your data never leaves your device. The tool is ideal for securing WordPress, Shopify, Google Search Console, Cloudflare, and databases. Protect your SEO value and prevent brute-force attacks by using a unique, uncrackable password for every service.
Cryptographically secure passwords from the Web Crypto API
Random mode uses window.crypto.getRandomValues — the same CSPRNG that powers TLS in modern browsers — to produce passwords between 8 and 64 characters with lowercase, uppercase, digits, and special characters toggled independently, plus an exclude-similar-characters option to avoid confusion between O/0 and l/1. An entropy estimate is shown next to every generated password so you can verify at a glance that 16 mixed characters really do carry around 96 bits of strength. Batch mode generates up to 100 passwords in one click, ideal for provisioning new team members or rotating service accounts.
EFF-style passphrases that are easy to type and remember
Passphrase mode picks 3 to 10 words from a 240-word EFF-style public-domain wordlist and joins them with your choice of hyphen, underscore, dot, space, or no separator, with an optional capitalize toggle. Because passphrases like "cellar-adopt-capital-candle" pack over 70 bits of entropy while remaining typeable on a phone keyboard, they are a better fit for master passwords and shared account credentials than 20-character random strings. The wordlist and all generation happen locally — your future passwords are never sent over the network.
