Open ProvincesPassword strength checker
Estimate how strong a password is and see what weakens it. The analysis runs in your browser: the password is neither sent nor stored.
As a precaution, do not enter the exact password of an important account: test a similar one instead. Nothing is transmitted, but it is a good habit.
Type a password to evaluate it.
How to read the result
The tool computes an estimate in “bits”: the higher the number, the more guesses it would take to find the password. It starts from the number of characters and the types of characters used, then subtracts points for predictable habits: repetitions, sequences such as 1234 or qwerty, very common words (even with @ for a or 0 for o), years and patterns like “a word followed by digits”.
The time shown assumes a very fast offline attack, for example after a database leak where passwords are poorly protected. A well-configured site limits online attempts, so the real risk is often lower, but this cautious assumption is useful for comparing.
Limits
- It is an estimate. It does not check public leaks: a password rated strong here may still have leaked if it is reused.
- The list of common words is short. It catches the most widespread cases, not all of them.
- A good score does not replace good practice: a different password for each account and two-factor authentication matter more.
What to do next
For a truly random password, use the secure password generator and store the result in a password manager. The Canadian Centre for Cyber Security also publishes current advice.
Frequently asked questions
Is my password transmitted when I type it here?
No. The calculation is done by the page’s JavaScript in your browser. No request is sent with what you type.
What length should I aim for?
At least 12 characters for an ordinary account and 14 or more for an important one. Length matters more than complicated symbols.
Is a passphrase a good idea?
Yes, if it is made of several randomly chosen words, not a well-known quote. It is easier to remember than a string of symbols.
