Test Your Password Security

Protecting your online accounts starts with a strong password. Our Password Strength Checker helps you evaluate the security of your password and provides real-time feedback to improve its strength.

Why Use Our Password Strength Tester?

• Instant Analysis: Get immediate feedback on how strong your password is.
• Advanced Security Checks: Detects dictionary-based words, common patterns, and symbol usage.
• Cracking Time Estimation: See how long it would take for a hacker to crack your password.
• 100% Safe & Private: Your password is never stored or transmitted; all calculations are done locally.

How Does This Password Strength Checker Work?

Our tool uses real-world hacking techniques to estimate password security:

• Brute Force ResistanceMeasures password randomness and length.
• Dictionary Attack DetectionIdentifies common words or predictable patterns.
• Symbol & Number UsageAnalyzes complexity for stronger protection.
• Offline vs. Online Cracking TimeShows how fast a hacker can break your password in different attack scenarios.

Offline vs. Online Password Cracking - What’s the Difference?

When we estimate password strength, it’s important to consider two different types of attacks:

Online Attacks (Slow, But Targeted)

• Happens when an attacker tries to log in to a website or service.
• Limited by security measures like rate limiting, CAPTCHA, and account lockouts.
• Attack speed: Around 1 million guesses per second (10⁶ guesses/sec).
• Example: Brute-forcing a Gmail, Facebook, or bank account login.
• Cracking time: Can take minutes to years depending on the strength of the password.

Offline Attacks (Fast & Extremely Dangerous)

• Happens when hackers steal a database of hashed passwords (e.g., from a data breach).
• No security restrictions (they can try billions of guesses per second).
• Uses powerful graphics cards (GPUs) and AI-powered password cracking tools.
• Attack speed: Around 100 trillion guesses per second (10¹⁴ guesses/sec).
• Example: A hacker steals encrypted passwords from a leaked database and cracks them without limits.
• Cracking time: A weak password can be cracked in seconds, while a strong one can take centuries.

How to Stay Safe from Offline and Online Attacks?

• Use Long, Random Passwords At least 16+ characters with uppercase, lowercase, numbers, and symbols.
• Enable Two-Factor Authentication (2FA) Even if your password is stolen, 2FA adds an extra security layer.
• Never Reuse Passwords Hackers often use previously leaked passwords to attack new accounts.
• Use a Password Manager This helps you generate and store complex passwords securely.
• Be Aware of Data Breaches Check your email on Have I Been Pwned? to see if your accounts were exposed.

Final Thoughts

• Online attacks are limited but still dangerous, especially if your password is weak.
• Offline attacks are much faster and can crack millions of passwords in minutes if they are not strong enough.
• The best defense is to use a long, unique, and complex password for every account.
