Password Strength Checker

Check If Your Password Is Too Easy to Guess

Use this free Password Strength Checker to check whether a password looks weak, fair, good, strong, or very strong. The tool checks password length, lowercase letters, uppercase letters, numbers, symbols, repeated characters, common passwords, keyboard patterns, year patterns, and overall password risk.

A strong password should be long, unique, and hard to guess. This tool gives a simple educational estimate so you can understand whether your password needs improvement before using it for an account.

What Is a Password Strength Checker?

A Password Strength Checker is an online tool that analyzes a password and gives a simple strength score. It helps you understand whether a password is too short, too common, predictable, repeated, or missing useful variety.

This tool does not guarantee that a password is impossible to crack, but it can help you avoid weak password habits such as using “password123,” “qwerty,” “123456,” names, birth years, repeated characters, or simple keyboard patterns.

Why Password Length Matters

Password length is one of the most important parts of password strength. A longer password is usually harder to guess than a short password, especially when it is not predictable.

For example, a short password with a few symbols may still be easier to guess than a longer passphrase made from random words. Instead of relying only on symbols, try to make your password longer and less predictable.

For important accounts, use a long password or passphrase whenever possible.

What Makes a Password Weak?

A password may be weak if it is short, common, reused, predictable, or based on personal information.

Weak password examples often include:

• 123456
• password
• password123
• qwerty
• admin
• welcome123
• name plus birth year
• phone number
• repeated characters
• keyboard patterns
• simple dictionary words

Hackers often try common passwords, leaked passwords, names, dates, keyboard patterns, and simple variations first. That is why predictable passwords are risky even when they contain numbers or symbols.

What Makes a Password Strong?

A strong password is long, unique, and difficult to guess. It should not be based on your name, birthday, phone number, pet name, company name, username, or common words.

A strong password usually has:

• Good length
• Randomness
• Uniqueness
• No obvious personal information
• No common password words
• No keyboard patterns
• No repeated characters
• No reuse across accounts

You can also use a password manager to create and store strong unique passwords for every account.

Password Strength Score Explained

This tool gives a score from 0 to 100.

A low score means the password is weak, short, common, or predictable.

A medium score means the password has some useful elements but still needs improvement.

A high score means the password looks stronger in this basic browser check.

The score is educational only. It should not be treated as a guarantee that a password is completely safe.
