What is a Password Generator?
A password generator is a tool that creates strong, random passwords automatically. Instead of trying to think of a secure password yourself, a password generator uses cryptographic algorithms to create truly random combinations of letters, numbers, and symbols that are virtually impossible to guess or crack.
Our free online password generator uses the Web Crypto API, which provides cryptographically strong random values. This ensures that every password generated is truly random and secure, making it an essential tool for protecting your online accounts.
How to Use This Password Generator
- Choose Password Length: Select a length between 4 and 128 characters. We recommend at least 12 characters for strong security.
- Select Character Types: Choose which character types to include - uppercase letters (A-Z), lowercase letters (a-z), numbers (0-9), and symbols (!@#$%).
- Optional Settings: Enable "Exclude Ambiguous Characters" to avoid characters that look similar (like i, l, 1, L, o, 0, O).
- Set Quantity: Choose how many passwords to generate (1-10) if you need multiple passwords.
- Generate: Click the "Generate Password" button to create your secure password(s).
- Copy: Click the "Copy" button to copy the password to your clipboard.
Why Use a Random Password Generator?
1. Stronger Security
Human-created passwords are predictable. We tend to use common words, dates, or patterns that hackers can easily guess using dictionary attacks or brute force methods. A random password generator creates truly random combinations that are exponentially harder to crack.
2. Avoid Password Reuse
With a password generator, you can easily create unique passwords for every account. Password reuse is one of the biggest security risks - if one account is compromised, all accounts using the same password are vulnerable.
3. Save Time
Coming up with strong passwords manually is time-consuming and mentally taxing. A password generator creates secure passwords instantly, saving you time and effort.
4. Meet Security Requirements
Many websites require passwords with specific criteria (minimum length, special characters, etc.). Our generator lets you customize these options to meet any requirement.
Password Strength Guidelines
| Length | Strength | Time to Crack |
|---|---|---|
| 4-7 characters | Weak | Instantly to minutes |
| 8-11 characters | Fair | Hours to days |
| 12-15 characters | Good | Months to years |
| 16+ characters | Strong | Centuries+ |
Best Practices for Password Security
- Use a Password Manager: Store your generated passwords in a reputable password manager like 1Password, LastPass, or Bitwarden.
- Enable Two-Factor Authentication (2FA): Add an extra layer of security to your accounts with 2FA or MFA.
- Never Share Passwords: Don't share passwords via email, text, or messaging apps.
- Change Passwords Regularly: Update passwords for sensitive accounts every 3-6 months.
- Use Unique Passwords: Never reuse passwords across different accounts.
- Avoid Personal Information: Don't use birthdays, names, or other easily guessable information.
- Check for Breaches: Use services like Have I Been Pwned to check if your accounts have been compromised.
Common Password Mistakes to Avoid
- ✗Using "password", "123456", or other common passwords
- ✗Using personal information (name, birthday, pet's name)
- ✗Using keyboard patterns (qwerty, asdf, 12345)
- ✗Reusing the same password across multiple sites
- ✗Storing passwords in plain text files or sticky notes
Frequently Asked Questions
Is this password generator safe to use?
Yes, absolutely. All password generation happens locally in your browser using the Web Crypto API. No passwords are ever sent to our servers or stored anywhere. The passwords exist only in your browser's memory.
How long should my password be?
We recommend at least 12 characters for most accounts, and 16+ characters for sensitive accounts like email, banking, or work accounts. Longer passwords are exponentially more secure.
Should I include symbols in my password?
Yes, including symbols significantly increases password strength by expanding the character set. However, length is more important than complexity - a 16-character password with only letters and numbers is stronger than an 8-character password with all character types.
How do I remember these complex passwords?
You shouldn't try to remember them! Use a password manager to securely store all your passwords. You'll only need to remember one master password for the password manager itself.
Can I use the same password for multiple accounts?
No, never reuse passwords. If one account is compromised, all accounts with the same password become vulnerable. Use our generator to create unique passwords for each account.
