shield Why You Need a Strong Password

Data breaches expose billions of credentials every year. In 2023 alone, over 8.2 billion records were leaked worldwide. The most common passwords—123456, password, qwerty—can be cracked in under 1 second.

A strong, unique password for each account is your first line of defense. But humans are notoriously bad at creating truly random passwords. We tend to reuse words, add predictable patterns (like Password1!), and use personal info that attackers can easily guess.

This tool solves that problem by generating passwords that are both cryptographically secure (using crypto.getRandomValues()) and easy to remember through mnemonic techniques like word substitution and passphrases.

tips_and_updates Password Security Tips

key
Use unique passwords
Never reuse passwords across different sites. If one gets breached, all accounts are safe.
text_increase
Longer is better
Aim for 16+ characters. Every extra character exponentially increases crack time.
lock
Use a password manager
Store generated passwords in a reputable password manager like 1Password, Bitwarden, or KeePass.
verified_user
Enable 2FA / MFA
Two-factor authentication adds a second layer of protection even if your password is compromised.
block
Avoid personal info
Don't use birthdays, pet names, or addresses — attackers check these first using social engineering.
sync
Rotate critical passwords
Change passwords for banking and email accounts every 3-6 months, or immediately after a breach.
search
Check for breaches
Use haveibeenpwned.com to check if your email or passwords have been exposed in known breaches.
description
Try passphrases
A 4-5 word passphrase like Coral-Haven-Prism-42 is strong AND easy to type on any device.
wifi_off
This tool runs offline
All passwords are generated 100% in your browser. Nothing is sent to any server — check the source code yourself.
security
Mix character types
Combine uppercase, lowercase, digits, and symbols to maximize entropy and resist dictionary attacks.

psychology How This Tool Works

psychologyMemorable Mode

Enter words you can remember (e.g., "blue ocean sunset"). The tool applies leet-speak substitution (a→@, e→3, s→$) with random case changes and optional symbols/numbers to create a password that looks complex but feels familiar. Three intensity levels control how aggressively characters are transformed.

casinoRandom Mode

Generates a fully random string using cryptographically secure randomness. Customize length (8–64 chars), character sets, and optionally exclude visually ambiguous characters (0/O, 1/l/I) for easier manual entry.

pinPIN Mode

For numeric-only codes (ATM pins, phone locks). Supports 4–12 digit PINs with options to prevent repeated digits and sequential patterns (123, 987) that are easy to guess.

descriptionPassphrase Mode

Picks 3–8 random words from a curated 100-word dictionary. Passphrases like Coral-Haven-Prism-Tiger-42 offer high entropy with excellent memorability — recommended by security experts including XKCD #936.
