A password strength checker tests how hard your password is to guess or crack. It looks at the length of your password and whether it mixes small letters, capital letters, numbers and symbols, then gives you a score from 0 to 100 and a rating from Weak to Strong. This free password strength checker also tells you exactly what to fix. It runs completely in your browser, so your password is never sent, stored or saved anywhere.
Weak passwords are the most common reason accounts get hacked. People reuse the same simple password everywhere, use their name or birthday, or pick passwords like "password123" that attackers try first. A strong password is long, random and different for every account. Checking your password here takes ten seconds and can save you from losing an email, bank or social media account. If your password scores Weak or Fair, use our Password Generator to make a strong one instead.
Try the password "password123". It is 11 characters long, so it gets some points for length, but it has only small letters and numbers, no capitals and no symbols, and it is one of the most common passwords in the world. This checker gives it a very low score and the rating Weak. Now try "Tr7$kQ9!zX2". It is 12 characters long and mixes capitals, small letters, numbers and symbols, so it scores near the top and earns the rating Strong. An attacker guessing at a billion passwords per second would need centuries to crack the second one, but only seconds to crack the first.
The score starts at zero and adds points: up to 45 points for length (8 or more characters, with extra points at 12 and 16), 10 points each for small letters, capital letters and numbers, and 15 points for symbols, for a total of 100. A very common password, such as "password", "123456" or "qwerty", is capped at 20 points no matter how it is written. The rating is Weak below 30, Fair from 30 to 54, Good from 55 to 79, and Strong at 80 and above. Length matters most: each extra character multiplies the number of possible passwords.
Use 12 characters or more. A 12-character password with mixed characters is far stronger than an 8-character one. Mix all four types. Small letters, capitals, numbers and symbols together make guessing much harder. Never reuse a password. If one site leaks your password, every other account with the same password is at risk. Avoid names and birthdays. Attackers try your name, your pet's name and your birthday first. Use a password manager. It can remember a different strong password for every site, so you only remember one master password.
Try the password "Sunshine2026" in the checker above. It is 12 characters long and mixes capital letters, small letters and numbers, so it scores about 65 out of 100 and earns the rating Good. Now add one symbol at the end to make "Sunshine2026!" and check again: the score rises to about 80 and the rating becomes Strong. One symbol makes a real difference, because it adds a whole new set of characters an attacker must try. Even better, make the password longer and less predictable, for example by using three random words with numbers and symbols mixed in.
Using a pet's name or birthday. Attackers try personal details first, because they are easy to find on social media. Adding "123" to a weak password. "sunshine123" is barely stronger than "sunshine", because attackers try number endings first. Reusing one good password everywhere. Even a strong password becomes weak if you use it on many sites, because one leak exposes them all. Writing passwords on paper near your computer. Anyone who visits your desk can read them. Trusting the score alone. A password can score well and still be unsafe if you share it or reuse it, so keep it secret and unique.
Pro Tip: A passphrase of three random words, such as "correct horse battery" with a number and a symbol added, is both strong and easier to remember than a random jumble of letters.
Note: The score is a guide, not a guarantee. A password's safety also depends on keeping it secret, using it on only one site, and changing it if a site is hacked.
What is a strong password? A strong password is at least 12 characters long and mixes small letters, capital letters, numbers and symbols. It is random, not a word or a date, and it is different from your other passwords.
Is it safe to type my password here? Yes. The check happens in your browser only. Your password is never sent to our servers, stored, or saved anywhere, and closing the page erases it.
Why is "password123" weak even though it has 11 characters? Because it is one of the most common passwords in the world. Attackers try common passwords first, so length alone does not help if the password is predictable.
How long should my password be? At least 12 characters is good, and 16 or more is even better. Every extra character makes the password much harder to crack.
Should I change my passwords often? Change a password at once if a site tells you it was hacked or if you used the same password elsewhere. Otherwise, a long, unique password does not need to be changed every month.
What is the difference between this checker and a password generator? The checker tests a password you already have. The generator creates a new random strong password for you. Use the checker first, and if your password is weak, use the generator to make a better one.
What score should I aim for? Aim for 80 or above, which earns the Strong rating. A score of 55 to 79 is Good, but adding a few more characters or a symbol will make it Strong.
Is a long simple password better than a short complex one? Usually yes. A 16-character password of only small letters can be stronger than an 8-character password with symbols, because length matters most.
