Common Questions
How to create a strong password? Recommend using at least 12 characters, combining uppercase and lowercase letters, numbers, and special symbols. Avoid personal information, common words, or keyboard patterns. Use unique passwords for each important account and change them regularly.How accurate is the password analysis? Our Password Strength Analyzer is based on the latest cryptography research, considering multiple dimensions including length, complexity, and entropy. The algorithm has been validated through numerous real cases and can accurately assess password security under current computational capabilities.
Will entered passwords be saved? Absolutely not. All analysis calculations are performed locally in your browser without sending password data to any server. When you close the page, all information is automatically cleared, ensuring your password security.
