A password generator creates random passwords from your chosen length and character types. It helps you avoid weak, reused, and predictable passwords when securing online accounts. Use it instead of passwords based on names, dates, or common words.
Our Password Generator quickly creates strong, random passwords with customizable security options.
Choose the password length, letters, numbers, symbols, and exclusions.
Generate a strong random password and view its strength and entropy.
Copy your generated password for secure use.

Password entropy measures how hard a password is to guess. More length and randomness create more possible combinations, making guessing harder. Higher entropy means attackers have more passwords to test.
A random 16 character password creates many more combinations than a short common password. With 94 printable characters, 16 random characters create about 3.7 × 10^31 combinations.
A strong password is long, random, unique, and hard to guess. Avoid names, birthdays, common words, repeated patterns, and passwords used on other accounts. Use a password manager to store unique credentials safely. Use one for every login.
Long passwords usually provide more security than short passwords. Complexity adds variety, but length and randomness remain key factors.
Password Length | Character Complexity | Security Level | Best Use |
|---|---|---|---|
8 characters | Mixed | Lower | Use only when required |
12 characters | Mixed and random | Better | Basic accounts |
16 characters | Mixed and random | Strong | Most accounts |
20+ characters | Mixed and random | Very strong | High value accounts |
Note: Use long, random, unique passwords whenever possible. A password manager can store them safely, so you do not need to memorize every password.
Use free security tools to check passwords, hashes, URLs, IPs, and other data for safer and faster online tasks each day.
