🔑 Security Basic Tool
Password Strength Analyzer
Test any password's strength against real-world attack scenarios. See its entropy, estimated time-to-crack, and actionable improvement suggestions. Note: calculations happen entirely in your browser — your password is never sent to any server.
⚠️ This is a client-side analysis only. While we don't transmit your password, avoid entering actual production or sensitive account passwords into any online tool. Use passphrases (4+ random words) for better usability and security.
