Check if a website has valid SSL/TLS certificate. Verify HTTPS connection and get tools for detailed certificate analysis
Analyze any URL for phishing, suspicious patterns, and security risks. Detects login keywords, suspicious TLDs, encoded characters, brand impersonation, and more
How strong is your password, really? Paste it in and find out. This checker estimates crack time, flags common patterns like dictionary words and keyboard walks, and suggests specific improvements. Everything runs locally — your password never leaves the page.
Rather than just counting character types, this checker analyzes entropy, pattern recognition, and dictionary matches to provide a realistic strength estimate. It catches sequences ("abcd"), repeated characters, common substitutions ("p@ssw0rd"), dates, and keyboard patterns that automated cracking tools exploit first.
Check whether your current passwords hold up against modern cracking techniques.
Test candidate passwords against your organization's strength requirements before deploying them.
Demonstrate to colleagues why "Summer2024!" is weaker than it looks.
No. All analysis happens in your browser. Nothing is sent to any server.
Length alone isn't enough. If the password contains common words, patterns, or predictable substitutions, cracking tools will find it quickly.
Length plus randomness. A 20-character random string is far stronger than a short string with every character type.
All processing happens directly in your browser. Your files never leave your device and are never uploaded to any server.
