🛡️ Why password strength matters
A weak password can be cracked in seconds, putting your email, bank, and social media at risk. Strong passwords use a mix of uppercase, lowercase, numbers, and symbols – and they're long (at least 12 characters). Our password strength checker analyzes your password in real time and shows you exactly where it's lacking.
We never store or transmit your password. The check runs entirely in your browser, so you can test even your most sensitive passwords with peace of mind.
🔑 How to create a strong password
- Length: at least 12 characters
- Mix it up: uppercase, lowercase, numbers, symbols
- Avoid common words: "password", "123456", your name
- Don't reuse: use a unique password for each account
- Consider a passphrase: a random sequence of words (e.g., "correct horse battery staple")
