Password Generator

Weak passwords are the #1 cause of data breaches—81% of hacking-related breaches involve weak or stolen passwords. Our Password Generator creates cryptographically secure, high-entropy passwords that resist brute-force attacks, dictionary attacks, and rainbow table lookups. Password entropy (bits) = log2(character_pool_size ^ length). Character pool sizes: numbers only = 10, lowercase = 26, uppercase+lowercase = 52, +numbers = 62, +symbols = 95+. Cracking time estimates: 8 chars full set = ~2 minutes, 12 chars = ~75 million years, 16 chars = ~10^23 years. Recommended lengths: general websites = 12 chars, email/banking = 14-16 chars, password manager master = 20+ chars. Features include custom length (4-64 chars), character type selection (uppercase, lowercase, numbers, symbols), exclude ambiguous characters (0,O,1,l,I), 4-character grouping with hyphens, real-time entropy calculation and strength indicator, clipboard copy with auto-clear, multiple generation modes (Standard, Pronounceable, Diceware), bulk generation (up to 100 passwords), and constraint presets (Web-safe, Bank-safe, Wi-Fi). Use with a password manager like Bitwarden, 1Password, or Apple Keychain.

Password Generator is optimized for fast browser-based use, so you can test multiple scenarios in seconds.
