Password strength isn't just about complexity rules — it's about how hard a password would be for an attacker to guess or crack using automated tools. This checker evaluates your password against several key factors and gives instant feedback, all directly in your browser without sending your password anywhere.

• Type a password into the input box.
• Watch the strength meter and checklist update instantly as you type.
• Review which criteria your password meets and which it's missing.

• Length — longer passwords are exponentially harder to crack through brute force.
• Character variety — mixing uppercase, lowercase, numbers, and symbols increases the pool of possible combinations.
• Common weak patterns — checks against well-known weak passwords like "password" or "123456" that appear at the top of every attacker's guess list.

Weak passwords remain one of the most common causes of account compromise. Automated cracking tools can try billions of guesses per second against leaked password hashes, meaning short or predictable passwords offer very little real protection, even if they "feel" complex to the person who chose them.

Is my password sent to your server?
No. This check runs entirely in your browser using JavaScript — your password is never transmitted anywhere, which is why it's safe to test your actual passwords here.

My password passed every check — is it guaranteed safe?
No tool can guarantee absolute safety, since real-world risk also depends on factors like password reuse across sites and whether a service you use has been breached. This checker measures resistance to guessing and cracking, which is one important factor among several.

What should I do if my password is weak?
Consider using our Password Generator or Passphrase Generator to create a stronger replacement, and enable two-factor authentication wherever available.
