Strong passwords are 12+ characters with a mix of upper/lowercase, numbers, and symbols - and unique per site. Our generator uses your browser's crypto.getRandomValues() for true randomness (not Math.random, which is predictable), shows entropy in bits, and estimates crack time so you can see exactly how strong each password is.
When to use this
Use for: new account signups, replacing a reused password that just got breached, bank and banking-app PINs (numeric mode), API keys and dev tokens, encrypted-archive passwords. Pair with a password manager - never memorize a strong password.
Frequently Asked Questions
How long should a password be?
12 characters is the modern minimum (NIST recommendation). 16+ for high-value accounts (bank, email, password manager). Length matters more than complexity - a 16-char lowercase-only password is stronger than an 8-char with symbols.
Is the password sent anywhere?
No. Generation happens entirely in your browser using crypto.getRandomValues(). Nothing is logged, transmitted, or stored. Once you close the tab, the password is gone unless you save it.
