Online Password Generator - Create Strong, Secure Passwords

How does the password generator work?

Our online password generator uses the cryptographically secure algorithm crypto.getRandomValues() to create truly random passwords. Unlike simple generators using Math.random(), our tool provides entropy suitable for security purposes. Each password is unique and generated directly in your browser – no data leaves your computer, ensuring absolute privacy protection.

Security First

All generation takes place locally on your device. Passwords are never sent to the server, stored in a database, or shared with third parties. Once you leave the page or refresh the browser, the generated password disappears.

Why do you need a strong password?

In an age where cyberattacks are becoming increasingly sophisticated, a strong password is your first line of defense. Weak passwords like “password123” or “qwerty” can be cracked in a matter of seconds using a brute-force method. A strong password with a combination of different character types significantly increases the time required to crack it – from a few seconds to thousands of years.

Most Common Security Mistakes

  • Password Reuse – Using the same password in multiple places means that compromising one account jeopardizes all others
  • Dictionary Passwords – Passwords based on common words can be cracked by a dictionary attack
  • Personal Information – Names, birth dates, or pet names are easily guessable
  • Short Passwords – Passwords shorter than 12 characters are more susceptible to cracking
  • Keyboard Patterns – Sequences like “asdfgh” or “147258” are very common

Tips for Secure Passwords

Ideal Password Length

  • 8-11 characters – Minimal, suitable only for less important accounts
  • 12-15 characters – Recommended length for most accounts
  • 16+ characters – Excellent for financial services, emails, and important accounts
  • 20+ characters – Maximum security for password managers and sensitive systems

Password Composition

Combine all character types for maximum security:

  • Uppercase Letters (A-Z) – Adds 26 possibilities per position
  • Lowercase Letters (a-z) – Another 26 possibilities
  • Numbers (0-9) – 10 additional possibilities
  • Special Characters (!@#$%) – Significantly increases complexity

Password Management

A strong password is useless if you cannot remember it or store it securely:

  1. Use a password manager – Tools like Bitwarden, 1Password, or KeePass allow you to store hundreds of unique passwords
  2. Two-Factor Authentication (2FA) – Adds an extra layer of security even if the password is compromised
  3. Regular Updates – Change passwords every 6-12 months, especially for important accounts
  4. Unique Password for Each Account – Never recycle passwords across different services

How to Create a Memorable Strong Password?

If you don’t want to use a password manager, there’s the passphrase method:

  1. Choose 4-5 random words: Cat-Green-Tree-Fish-64
  2. Combine them with unusual characters: Cat!Green@Tree#Fish$64
  3. Add numbers and modifications: C@t!Gr33n@Tr33#F1sh$64

Such a phrase is easy to remember but very difficult to crack.

Frequently Asked Questions (FAQ)

Is this password generator really secure? Yes, all generation occurs locally in your browser using the Web Crypto API. Passwords are never sent to the server.
How often should I change my passwords? For regular accounts, every 6-12 months is sufficient. After any security incident (data breach), change the password immediately.
How many characters should a password have? At least 12 characters. For important accounts, we recommend 16 or more characters.
Can I use the same password for multiple accounts? Never! Each account should have a unique password. Use a password manager to manage them.
What if I forget my password? That's why we recommend password managers. Alternatively, write down passwords on paper and keep them in a safe place (not near the computer).

Recommendations for Specific Services

Bank Accounts and Finance

  • Minimum 16 characters
  • All character types (uppercase, lowercase, numbers, symbols)
  • Unique password only for this account
  • Activate 2FA (two-factor authentication)
  • Change every 6 months

Email Accounts

  • Minimum 14 characters
  • Email is the key to resetting other passwords
  • Use a different password than for other services
  • Mandatory 2FA activation
  • Regular check of logged-in devices

Social Networks

  • Minimum 12 characters
  • Protection against phishing and account takeover
  • Activate 2FA via app (not SMS)
  • Regularly check active sessions

Work Accounts

  • According to company standards (usually 14+ characters)
  • Never use personal passwords
  • Change when leaving the company
  • Do not store on work devices

Dangerous Password Practices

Storing passwords in a notepad

Do not store passwords in a passwords.txt file on the desktop

Instead, use an encrypted password manager

Sharing passwords via email or SMS

Never share passwords via unsecured channels

Instead, use secure tools like Bitwarden Send

Browser as a password manager

⚠️ Risky - browsers often don’t use strong encryption

Better is a dedicated password manager with a master password

Writing passwords on paper

⚠️ Acceptable if you keep the paper in a safe or locked drawer

Unacceptable sticking it on the monitor or under the keyboard

Password Strength Testing Tools

After generating a password, you can test its strength at:

  • haveibeenpwned.com - Find out if your password has been exposed in a data breach
  • password.kaspersky.com - Password cracking time calculator

Warning: Never enter your actual password on unknown websites!

What to do if your password is leaked?

  1. Immediately change your password on all accounts where you used it
  2. Activate 2FA wherever possible
  3. Check account activity and log out unknown devices
  4. Monitor suspicious activity on bank accounts
  5. Set up alerts for unusual logins
