Privacy Notice
Your password is generated entirely in your browser using cryptographically secure random generation. We never send or store your passwords on our servers.
How to Create a Strong Password
Use 12+ Characters
Security experts recommend passwords be at least 12-16 characters long. Each additional character exponentially increases the time it would take to crack your password. Our password generator supports up to 128 characters for maximum security.
Mix Character Types
Include uppercase letters (A-Z), lowercase letters (a-z), numbers (0-9), and symbols (!@#$%^&*). This creates a larger character pool, making your password much harder to crack through brute force attacks.
Avoid Personal Information
Never use names, birthdays, addresses, or other personal information that could be found on social media or through public records. Our random password generator creates completely random passwords with no patterns or personal connections.
Never Reuse Passwords
Use a unique password for every account. If one account is compromised, reused passwords put all your other accounts at risk. Generate a new secure password for each service.
Password Security Best Practices
🔐 Use a Password Manager
Store your generated passwords in a reputable password manager like 1Password, LastPass, or Bitwarden. This allows you to use unique, complex passwords without memorizing them all.
🔑 Enable Two-Factor Authentication
Even with a strong password, enable 2FA (two-factor authentication) on all accounts that support it. This adds an extra layer of security beyond your password.
🔄 Change Passwords Regularly
Update passwords for critical accounts every 3-6 months. Always change passwords immediately if you suspect a breach or receive a security alert from a service.
🚫 Never Share Passwords
Never share passwords via email, text message, or any other communication method. Legitimate services will never ask for your password.
Password Generator Settings and Options
Password Length (8-128 characters)
Adjust the slider to set your desired password length. Longer passwords are more secure. We recommend at least 16 characters for important accounts like email, banking, and work accounts.
Include Uppercase Letters (A-Z)
Adds capital letters to your password, increasing complexity. Most services require at least one uppercase letter.
Include Lowercase Letters (a-z)
Adds lowercase letters to your password. Essential for creating pronounceable segments if needed.
Include Numbers (0-9)
Adds digits to your password. Most services require at least one number for password creation.
Include Symbols (!@#$%^&*)
Adds special characters to your password, significantly increasing strength. Note that some services may not accept all symbols - check the specific requirements.
Exclude Ambiguous Characters
Removes easily confused characters like i, l, 1, L, o, 0, O. Useful when you need to type the password manually or share it verbally.
Why Use a Random Password Generator?
🛡️ Maximum Security
Human-created passwords often contain patterns, dictionary words, or personal information that make them vulnerable to attacks. Our random password generator creates truly random passwords using cryptographically secure methods (crypto.getRandomValues API).
🎲 No Patterns or Predictability
Random passwords have no patterns, sequences, or predictable elements. This makes them resistant to dictionary attacks, rainbow table attacks, and social engineering attempts.
✅ Meets All Security Requirements
Our password maker automatically creates passwords that meet the strictest security requirements of most websites and services, including length, character variety, and complexity rules.
🚀 Protection Against Dictionary Attacks
Dictionary attacks try common words and phrases. Random passwords completely defeat this attack method because they contain no dictionary words or common phrases.
Understanding Password Strength
Weak Password Examples (Never Use These)
password, 123456, qwerty, letmein, welcome, admin
These passwords can be cracked in less than 1 second using modern tools.
Strong Password Examples
tK9$mP2#vL4&xR8, aB3!dE6@gH9#kL2, nQ7%pR4*sT8&vW5
These randomly generated passwords would take billions of years to crack with current technology.
Time to Crack Different Password Types
Entropy and Password Strength
Password strength is measured in bits of entropy. Higher entropy means more possible combinations and better security. Our password generator calculates entropy based on character set size and length, providing a real-time strength indicator.
How Hackers Crack Weak Passwords
Brute Force Attacks
Attackers try every possible character combination until they find the right password. Short passwords with limited character types can be cracked quickly. Use our strong password generator to create passwords that resist brute force attacks.
Dictionary Attacks
Hackers use lists of common words, phrases, and passwords to attempt login. Passwords like "password123" or "iloveyou" are cracked instantly. Random passwords are immune to dictionary attacks.
Rainbow Table Attacks
Pre-computed hash tables allow attackers to reverse password hashes quickly. While this affects how services store passwords, using strong random passwords makes even compromised hashes much harder to crack.
Social Engineering
Attackers gather information about you from social media to guess passwords containing personal details like names, birthdays, or pet names. Random passwords eliminate this vulnerability entirely.
Frequently Asked Questions About Password Security
How long should my password be?
Security experts recommend passwords be at least 12-16 characters long. Longer passwords are exponentially more secure. Our password generator supports up to 128 characters for maximum security. For critical accounts like email and banking, use at least 16-20 characters.
Is it safe to use this generator?
Yes! Your password is generated entirely in your browser using cryptographically secure random generation (crypto.getRandomValues). We never send or store your passwords on our servers. The generation happens client-side for complete privacy and security.
Should I use symbols in passwords?
Yes, including symbols significantly increases password strength by expanding the character set. However, ensure the website or service you're using accepts symbols in passwords. Some services have restrictions on which symbols are allowed.
How often should I change my password?
Change passwords immediately if you suspect a breach or receive a security alert. For regular accounts, changing passwords every 3-6 months is good practice, though using strong unique passwords with 2FA is more important than frequent changes. Never reuse old passwords.
What is the strongest password?
The strongest password is long (16+ characters), uses all character types (uppercase, lowercase, numbers, symbols), is completely random, and is unique to each account. Our secure password generator creates passwords that meet all these criteria. A 20-character password with all character types would take trillions of years to crack.
Can I trust online password generators?
You can trust reputable generators that generate passwords client-side (in your browser) without sending data to servers. Our generator uses the Web Crypto API (crypto.getRandomValues) for true random generation and never transmits your passwords. Always avoid generators that require account creation or seem suspicious.
What's better: random passwords or passphrases?
Both can be secure if done correctly. Random passwords (like those from our generator) offer maximum entropy per character. Passphrases (like "correct-horse-battery-staple") can be easier to remember but need to be longer. For accounts stored in a password manager, random passwords are superior. For master passwords you must remember, long random passphrases work well.
How do I remember all my passwords?
Use a password manager! Services like 1Password, LastPass, Bitwarden, or Dashlane securely store all your passwords behind one master password. This allows you to use unique, complex passwords for every account without memorizing them all. Most password managers also include built-in password generators.
