Advanced Password Security Checker
Analyze and strengthen your password security
Test Your Password Security
Password strength is evaluated based on multiple factors:
- Very Weak: Easily cracked, high risk
- Weak: Simple patterns, vulnerable
- Moderate: Better but still improvable
- Strong: Good security for most uses
- Very Strong: Excellent protection
Entropy measures password randomness. Higher is better.
- < 40 bits: Very weak
- 40-60 bits: Moderate
- 60-80 bits: Strong
- > 80 bits: Very strong

Common Password Mistakes
Using Personal Information
Avoid using birthdays, names, or other personal details in your passwords. Hackers can easily guess these.
Avoid Password Reuse
Using the same password across multiple sites is dangerous. If one site is compromised, all your accounts are at risk.
Short Passwords
Short passwords are easily cracked. Length adds significant security to your passwords.
Ignoring 2FA
Not using two-factor authentication when available leaves your accounts vulnerable even with strong passwords.
Manual Password Management
Trying to remember all your passwords often leads to weak or reused passwords. Password managers solve this problem.
Dictionary Words
Using common dictionary words makes your password vulnerable to dictionary attacks. Even with modifications like replacing letters with numbers, these are easily cracked.
Creating Secure Passwords
Use Passphrases
Create long, memorable phrases with random words, numbers, and symbols. For example: "PurpleTiger$2023!"
Unique Passwords
Use different passwords for each account to minimize the impact of a single breach.
Password Manager
Consider using a password manager to generate and store strong, unique passwords securely.
Enable 2FA
Add an extra layer of security by enabling two-factor authentication wherever possible. This protects your accounts even if your password is compromised.
Regularly Update Passwords
Change your passwords periodically to reduce the risk of long-term exposure.
Avoid Predictable Substitutions
Instead of replacing "o" with "0" or "a" with "@", use truly random combinations to make your password harder to guess.
General FAQ - Password Security & Protection
What is password entropy, and why is it important?
Password entropy measures the randomness and complexity of your password. A higher entropy score means your password is more secure and harder for attackers to guess using brute-force methods. It is essential to increase your password's entropy to protect against potential breaches. You can use an entropy password calculator or password entropy tester to measure your password's strength.
How can I create a strong password?
A strong password should be long (12+ characters) and include a mix of uppercase letters, lowercase letters, numbers, and special characters. Avoid using easily guessable information such as names, birthdays, or common words. Consider using a password strength tester tool to check your password's security before using it.
How do I check my password's strength?
You can use an online password strength checker to instantly analyze the strength of your password. The tool provides an estimation of how long it would take to crack your password and gives feedback on its entropy and overall security. For enhanced security, use the password strength checker tool integrated with entropy tests.
Why is two-factor authentication (2FA) important?
Two-factor authentication (2FA) adds an extra layer of security by requiring a second form of verification (such as a code sent to your phone or email) in addition to your password. This significantly reduces the risk of unauthorized access, even if your password is compromised.
Should I use a password manager?
Yes, a password manager helps you securely store and manage your passwords. It generates strong, unique passwords for each account and saves you from remembering them, all while keeping your data encrypted and safe. Many password managers also include a password security checker to evaluate your existing passwords.
How long does it take to crack a password?
The time to crack a password depends on its length and complexity. Short passwords with simple patterns can be cracked instantly, while long, complex passwords may take years or even centuries to break. Use a password strength tester to estimate the crack time based on your password's strength.
Can a password be too long?
While there is no such thing as a password being "too long" for security, excessively long passwords may be impractical. Generally, a password length of 12-16 characters is ideal for balancing security and usability. For critical accounts, always use a password entropy calculator to verify password security.
How often should I update my passwords?
It's a good practice to update passwords every 3-6 months, or sooner if you suspect any account may have been compromised. Regularly changing passwords minimizes the risk of unauthorized access. You can check your password strength and entropy every time you update it using a password security checker.
How can I protect myself from phishing attacks?
Phishing attacks often trick users into revealing their passwords or personal information. To protect yourself, avoid clicking on suspicious links, ensure the website's URL starts with "https", and use a password manager to prevent entering passwords on fake sites. Consider using a password entropy tester to check your passwords for extra security.
