Check password strength online — live strength meter and actionable feedback
The Password Strength Checker analyzes your password in real time and scores it based on five key criteria: length, uppercase, lowercase, numbers, and symbols. The tool uses secure, client-side logic — your password never leaves your browser. As you type, the strength meter updates to show a visual score and plain-language guidance on how to improve. The meter uses weighted scoring so length and variety have more influence than a single character change, providing a practical, human-friendly assessment of password security. For more detailed analysis, try our Password Character Set Analyzer to understand the composition of your password.
Using a strength checker helps you quickly evaluate whether a password is safe for sensitive accounts. It gives clear suggestions for improvement and helps you avoid common weak patterns like short lengths, missing character types, or using obvious words. This tool complements our password generator by allowing you to compare and improve passwords before you use them.
Use the Password Strength Checker whenever you create or update account credentials — before signing up for email, banking, social media, or work-related services. It’s also useful when auditing existing passwords to prioritize which ones to change first.

No. All checks are done locally in your browser. Nothing is transmitted to any server.
Passwords that are 12+ characters long and include uppercase, lowercase, numbers, and symbols are typically rated as strong or very strong.
It’s a helpful guide but not a guarantee. Combine strong passwords with unique passwords per site and two-factor authentication for best security.
Special characters help increase complexity, but length and unpredictability matter more than just adding symbols to a common word.
