Generate strong, random passwords — nothing is stored or sent anywhere
A 16-character password is exponentially harder to crack than an 8-character one. Aim for at least 12 characters.
Use a unique password for every account. If one gets compromised, the rest stay safe.
Tools like 1Password, Bitwarden, or Apple Keychain can store and auto-fill all your unique passwords.
Even the strongest password benefits from a second factor. Use an authenticator app when possible.
Humans are terrible at creating random passwords. We tend to use predictable patterns — dictionary words, birthdays, pet names, and simple substitutions like "p@ssw0rd." These are exactly the patterns that automated cracking tools exploit first. A truly random password generator eliminates human bias entirely.
Password strength is measured in entropy — the number of possible combinations an attacker would need to try. A 16-character password using uppercase, lowercase, numbers, and symbols has approximately 105 bits of entropy, which would take billions of years to brute-force with current technology. Our strength meter evaluates your password based on length, character variety, and complexity.
Yes. This password generator runs entirely in your browser using JavaScript's built-in cryptographic random number generator (crypto.getRandomValues). No passwords are ever sent to a server, stored, or logged. You can verify this by disconnecting from the internet — the generator still works perfectly.
For most accounts, 12 to 16 characters provides excellent security. For high-security accounts like your email, banking, or password manager master password, consider 20 or more characters. The longer the password, the exponentially more difficult it becomes to crack.
A strong password uses a mix of character types (uppercase, lowercase, numbers, and symbols), is at least 12 characters long, doesn't contain dictionary words or personal information, and is unique to each account. Our generator creates passwords meeting all of these criteria by default.
