Password Generator & Strength Analyzer

Generate strong passwords, or see how weak yours is.

Password Generator & Strength Analyzer gives you two tools in one: a generator that builds truly random passwords using your browser's cryptographic RNG, and an analyzer that computes real entropy in bits, estimated crack time under three realistic attack scenarios, and flags common weaknesses like dictionary words, keyboard-walk patterns, and repetition. Everything runs locally — no password ever leaves your browser.

• →Generates passwords with window.crypto.getRandomValues — never Math.random
• →Length slider from 8 to 64 characters with toggles for each character class
• →Optional 'exclude ambiguous characters' mode (0/O/l/1/I/|)
• →Analyzer computes true entropy and crack time for fast-hash, bcrypt, and online-throttled attacks
• →Flags common passwords, keyboard-walk patterns, and repeated characters
• →Watermarked by Cikal Studio Labs · Works on any device, no install required
