Password Security Tips

Using strong, unique passwords is one of the most important steps you can take to protect your online accounts. Here are some tips to enhance your password security:

🛡️

Use Different Passwords

Never reuse passwords across multiple accounts. If one service is compromised, all your accounts would be at risk. Create unique passwords for each service you use.

📏

Length Over Complexity

A longer password is generally more secure than a shorter, complex one. Aim for at least 12 characters, but 16-20 is even better for important accounts.

🧠

Use a Password Manager

Password managers securely store all your passwords, allowing you to use strong, unique passwords without having to memorize them all.

🔄

Enable 2FA

Two-factor authentication adds an extra layer of security beyond your password. Enable it on all accounts that offer this feature.

⚠️

Avoid Personal Information

Don't use personal details like your name, birthday, or pet names in your passwords. This information is often easy to find and can make passwords vulnerable.

🔔

Check for Breaches

Regularly check if your accounts have been involved in data breaches and change your passwords immediately if they have been compromised.

Tip #1: Create a Passphrase

Consider using a passphrase—a series of random words—instead of a traditional password. For example, "correct-horse-battery-staple" is both easy to remember and difficult to crack due to its length.

Tip #2: Check Your Password Strength

Use our password strength meter to evaluate how secure your passwords are. The stronger your password, the more resistant it is to various cracking methods.

Tip #3: Be Careful with Security Questions

Treat security questions like secondary passwords. Use fictional or unrelated answers that you'll remember but others can't easily guess or find online.

Tip #4: Update Critical Passwords

While frequent password changes are no longer recommended for all accounts, you should still update passwords for your most critical accounts (financial, email) periodically.

Tip #5: Use Generated Passwords

Humans are predictable, and we tend to follow patterns when creating passwords. Using a generator ensures truly random combinations that are much harder to guess or crack.

Check if Your Password Has Been Compromised

Have your accounts been involved in data breaches? Enter your email address to check if your information has been compromised in known data breaches. This uses the Have I Been Pwned API and is done securely.

Note: This will redirect you to HaveIBeenPwned.com, a trusted service for checking data breaches. We do not store your email address.

How Password Security Works

Understanding how password security works can help you make better decisions about your online security. Here's a simplified explanation of password storage and cracking methods:

How Passwords Are Stored

When you create an account on a website, your password isn't stored as plain text (at least it shouldn't be). Instead, it goes through a one-way mathematical process called "hashing." This converts your password into a fixed-length string of characters that looks completely random. When you log in, the site hashes what you entered and compares it to the stored hash—not your actual password.

Common Password Cracking Methods

Password Entropy and Strength

Password entropy measures how unpredictable a password is—essentially, how many guesses would be needed, on average, to find the correct password. Each type of character (lowercase, uppercase, numbers, symbols) you include increases entropy, as does increasing the length.

For example:

This is why our generator defaults to 16 characters with all character types enabled—it creates passwords with very high entropy that would take centuries to crack with current technology.

Password Managers: The Ultimate Security Tool

Using a password manager is one of the most effective ways to improve your online security. Here's why you should consider using one and some popular options:

Frequently Asked Questions

What makes a password strong? +

A strong password typically includes:

  • At least 12-16 characters in length (longer is better)
  • A mix of uppercase and lowercase letters
  • Numbers and special characters (symbols)
  • No common words, phrases, or predictable patterns
  • No personal information that could be easily guessed

The strength of a password is primarily determined by its length and randomness. Our password generator creates passwords with high entropy (randomness) to maximize security.

Why should I use a password generator? +

Humans are inherently bad at creating random, secure passwords. We tend to:

  • Use patterns that make passwords easier to remember but also easier to crack
  • Reuse passwords across multiple sites
  • Use personal information that might be easily discovered
  • Make simple substitutions (like "p@ssw0rd") that cracking algorithms can easily account for

Password generators create truly random combinations that are much more secure than human-created passwords. They eliminate the biases and patterns we naturally introduce when creating passwords ourselves.

How often should I change my passwords? +

Current cybersecurity best practices have moved away from recommending regular password changes on a fixed schedule (like every 90 days). Research has shown that forced frequent password changes often lead to weaker passwords or minor variations of the same password.

Instead, you should change your passwords:

  • Immediately if there's a known data breach affecting a service you use
  • If you suspect someone knows your password
  • When you've shared a password with someone who no longer needs access
  • If you've been using the same password for a very long time

Using unique, strong passwords for each service and enabling two-factor authentication where available is now considered more important than frequent password rotation.

Is it safe to use an online password generator? +

Our online password generator is safe because it generates passwords entirely in your browser - the passwords are never sent to our servers or stored anywhere.

However, for maximum security with extremely sensitive accounts (like primary email accounts or banking), consider:

  • Using an offline password generator
  • Using a reputable password manager that includes generation features
  • Generating passwords on a device that isn't connected to the internet

For most everyday accounts, our generator provides more than adequate security, especially when compared to creating passwords yourself.

How can I remember all my strong passwords? +

The truth is, you shouldn't try to memorize all your strong passwords. There are better options:

  • Use a password manager: This is the most secure and convenient option. You only need to remember one strong master password.
  • Create a password system: Develop a system for generating passwords that you can recreate when needed, but isn't obvious to others.
  • Use passphrases: For accounts where you must memorize the password, use a long passphrase that's meaningful to you but not obvious to others.
  • Write them down: For less critical accounts, writing passwords down and keeping them in a physically secure location can be acceptable (though not ideal).

A password manager remains the gold standard solution, as it handles both the generation and storage of strong, unique passwords for all your accounts.

Are password managers really secure? +

Reputable password managers are designed with security as their primary focus. They use strong encryption to protect your data, and in most cases, the companies behind them cannot access your actual passwords because of their "zero-knowledge" architecture.

While no system is 100% secure, password managers significantly improve your overall security compared to:

  • Reusing passwords across multiple sites
  • Using weak, easily remembered passwords
  • Storing passwords in unencrypted documents or notes
  • Using browser password storage (which is typically less secure)

The security benefits of using strong, unique passwords for each site far outweigh the theoretical risk of a password manager breach. Just be sure to use a very strong master password and enable two-factor authentication on your password manager account.
