Free Password Strength Checker

Test how strong your password is. All analysis happens in your browser — nothing is sent to a server.

What Makes a Password Strong?

A strong password is your first line of defense against unauthorized access. Cybercriminals use automated tools that can test millions of combinations per second.

The key factors are length, complexity, and uniqueness. Longer passwords with a mix of character types are exponentially harder to crack.

Length Matters

Each additional character multiplies the complexity exponentially. An 8-character password can be cracked in hours, while a 16-character one could take centuries.

Character Variety

Mix uppercase letters, lowercase letters, numbers, and symbols. Each new character set dramatically increases the number of possible combinations.

Avoid Common Patterns

Avoid using "password", "123456", "qwerty", or personal information like birthdates. Hackers use dictionaries of the most common passwords in their first wave of attacks.

Use a Password Manager

The best passwords are random strings you don't need to memorize. Password managers generate and store complex passwords for every site you use.
