Passwords: The Only Key to Your Digital World

Our social media accounts, emails, banking applications, and even internal confidential documents... There is only one wall protecting our digital identity and wealth: Our passwords. Unfortunately, however, more than 80% of cyber attacks today are caused by users using weak passwords that are child's play to guess, such as "123456", "qwerty", or their own birth dates.

Many people underestimate password security, saying "Why would anyone want my account?". However, hackers (cyber pirates) are not just interested in who you are; they use your account to include it in a zombie (bot) network and attack others, commit fraud, or take out a loan in your name through identity theft.

What is a Brute Force Attack?

If you think malicious people sit in front of the screen and guess passwords one by one to take over an account, you are wrong. Today, cyber attackers use massive AI-powered servers and software (Brute Force attacks) that can try billions of password combinations per second.

These attacks work as follows: The software tries all possible combinations of letters, numbers, and symbols on the keyboard sequentially (aaaa, aaab, aaac, etc.). They also use "Dictionary" lists containing billions of old passwords leaked to the market.

The Effect of Password Length on Cracking Time

The time it takes for a modern computer (or graphics card) to crack a password depends entirely on the number of characters and complexity:

  • A 6-character password consisting of only lowercase letters: Cracked instantly (0.1 seconds).
  • An 8-character password containing lowercase letters, uppercase letters, and numbers: Cracked in about 1 hour.
  • A 12-character password containing uppercase/lowercase letters, numbers, and symbols: Cracked in about 34,000 years!

Math does not lie. Every time the number of characters in your password increases, the time required for hackers to crack that password grows exponentially.

Test Your Password: Password Strength Meter Tool

Do you want to know how truly secure the password you are using is? You can use WebToolsDo's completely free Password Strength Meter tool to find out the danger level your password is in.

How Does Our Tool Work?

The moment you type your password on your keyboard, our tool runs an advanced entropy (complexity) algorithm in the background. This algorithm checks the following:

  1. Length: Is your character count sufficient? (At least 12-16 characters are recommended).
  2. Character Variety: Does your password have Uppercase Letters, Lowercase Letters, Numbers, and Special Symbols (!, @, #, $, %)?
  3. Dictionary Guesses: Does your password contain predictable patterns such as your name, consecutive numbers (1234), or keyboard layouts (qwe, asdf)?

The tool evaluates the password you typed with a score between red (Very Weak) and green (Very Strong) and gives you an instant result.

Privacy Warning: 100% Security Guarantee

The most frequently asked question about password testing tools is this: "What if you are saving the password I typed?"

The WebToolsDo Password Strength Meter tool runs entirely Client-side (in the Browser). No key you press on the keyboard, no letter, and no password you type is sent to our servers, our databases, or the internet. The verification process takes place entirely in the RAM memory of your computer and is deleted the moment you close the page.

How to Create an Uncrackable Password?

  1. Use a Passphrase, Not a Password: Instead of a hard-to-remember password like !Xy8#mP9, create a sentence that is easy to remember but very long. For example: TheBlueBirdFlewOnFriday! (It would take trillions of years to crack this password).
  2. Do Not Recycle the Same Password: Never use the same password for your Instagram, bank, and email accounts. If one gets hacked, your entire digital life will collapse like dominos.
  3. Two-Factor Authentication (2FA): No matter how strong your password is, absolutely activate the Two-Step Verification lock such as SMS or Google Authenticator on every account. This will protect your account even if your password is stolen.

Conclusion

Cyber security is an issue that seems unimportant until you get hacked, but can turn your life into a nightmare when it happens to you. If you lock your door, you should lock your digital identity as well. Test your existing passwords with the Password Strength Meter tool on our site right now, detect the weak ones, and protect yourself against cyber pirates in the digital world!
