Password strength

Password strength is how hard a password is to guess or crack; length and variety of characters matter.

In plain English

How hard your password is for someone (or a computer) to guess. Longer and mixed (letters, numbers, symbols) is stronger. Our password tool checks it in your browser—nothing is sent to our servers.

Password strength depends on length, character variety (uppercase, lowercase, numbers, symbols), and avoidance of common words or patterns. Strong passwords resist guessing and brute-force attacks.

Our password strength checker runs entirely in your browser and does not send what you type to our servers. Use it to see if your password meets common strength guidelines.
