Questions

Password Strength Analyser FAQ

How accurate is the password strength analysis provided by this tool?
The analysis uses the zxcvbn library, which estimates crack time based on real-world password patterns and common sequences, providing a more realistic assessment than simple character count methods.
Can I use this tool to check passwords I already use online?
It is safe to enter passwords for analysis as the tool runs locally in your browser and does not transmit data to servers, but users should still exercise caution with sensitive credentials.
What makes a password strong according to this analyzer?
A strong password typically has sufficient length, a diverse character set including uppercase, lowercase, numbers, and symbols, and avoids common words, names, or predictable patterns found in the zxcvbn database.
Does this tool store or transmit my password after analysis?
The analysis runs client-side in your browser; the password entered is not sent to the IT Tools website or stored anywhere, ensuring privacy for the user.
