What Is a Strong Password?
A strong password is one that resists brute-force attacks, dictionary attacks, and credential-stuffing attempts. Strength is measured by entropy, which increases with length and character variety. A 12-character password mixing uppercase, lowercase, numbers, and symbols has roughly 79 bits of entropy, making it practically impossible to crack with current hardware.
Most data breaches exploit weak or reused passwords. Attackers use automated tools that test billions of combinations per second, starting with common words, keyboard patterns, and previously leaked credentials. A random password generator removes human bias and produces truly unpredictable strings that resist these attack methods effectively.
Popular Use Cases
Online Account Creation
Generate unique passwords for every new account to prevent credential-stuffing attacks from leaked databases.
Database Credentials
Create high-entropy passwords for database users where a breach could expose millions of records.
API Keys and Tokens
Generate random strings for service-to-service authentication where predictability would be a critical vulnerability.
WiFi Network Passwords
Create memorable yet strong WPA3 passwords for home and office networks to prevent unauthorized access.
Password Security Tips
Use 16+ Characters Minimum
Modern GPUs crack short passwords quickly. NIST recommends at least 15 characters for high-security accounts.
Adopt a Password Manager
Tools like Bitwarden or 1Password store unique passwords for every site, so you only memorize one master password.
Enable Two-Factor Authentication
Even the strongest password can be phished. Add TOTP or hardware key 2FA to critical accounts as a second layer.
Avoid Personal Patterns
Never use birthdays, pet names, or keyboard walks like qwerty123. Attackers test these variations first.
Rotate After Breaches Only
Frequent forced rotation leads to weaker passwords. Change passwords when a service reports a breach, not on a schedule.
