Random Password Generator

Generate secure, random passwords effortlessly with our customizable online Password Generator. Tailor your password length and character sets—including lower/upper case letters, numbers, and symbols—while excluding ambiguous characters for maximum security. Password Length: Include Lower Case (a-z) Include Upper Case (A-Z) Include Numbers (0-9) Include Symbols (!"#$%&'()*+,-./:; ?@[\]^_`{|}~) Exclude Ambiguous Characters (iIl1L| o0O `'-_":;.,) Exclude Brackets (<>()[]{}) No Repeated Characters Save Settings Saved! body { font-family: Arial, sans-serif; background-color: #f4f4f4; padding: 20px; } .panel { background-color: #ffffff; border-radius: 10px; padding: 20px; box-shadow: 0 2px 10px rgba(0, 0, 0, 0.1); } input[type="checkbox"] { margin-right: 10px; } .verybigtext { font-size: 24px; color: #333; margin: 15px 0; } #resultid { font-size: 18px; margin-top: 20px; } /* Button styles for Copy Password and Regenerate */ .action-button { display: inline-block; padding: 10px 15px; font-size: 16px; text-decoration: none; border: none; border-radius: 5px; background-color: #17a2b8; /* Change color as necessary */ color: white; cursor: pointer; box-shadow: 0 2px 5px rgba(23, 162, 184, 0.3); margin: 5px; transition: background-color 0.3s, box-shadow 0.3s; } /* Highlight effect */ .action-button:hover { background-color: #138496; /* Darker shade for hover */ box-shadow: 0 4px 10px rgba(23, 162, 184, 0.5); } /* Responsive style */ @media (max-width: 600px) { h2 { font-size: 20px; } } function genMathRand() { if (window.crypto) { var tempGRArray = new Uint32Array(1); return (window.crypto.getRandomValues(tempGRArray) / 65536 / 65536); } else { return Math.random(); } } function saveSettings() { var frm = document.passForm; var cvalue = ''; cvalue += frm.ilower.checked ?
