A cryptographically secure, client-side password generator. No server requests — everything runs directly in your browser.

→ Live Demo

• Cryptographically secure — uses crypto.getRandomValues(), never Math.random()
• Flexible settings — password length from 4 to 128 characters, choose character sets (uppercase, lowercase, digits, special)
• Category guarantee — generated password always contains at least one character from each selected category
• Exclude ambiguous characters — removes l, 1, I, O, 0, o (enabled by default)
• Strength indicator — entropy-based calculation: Weak / Medium / Strong / Excellent
• Dark & light theme — persisted in localStorage
• Two languages — English and Russian, switch on the fly
• One-click copy — copies to clipboard with a toast notification
• Fully static — no backend, no tracking, no cookies
