Password Strength Checker FAQ
- Is my password safe to type into the checker?
- Yes, because the tool runs entirely on your device; no password data is sent to or stored by Inventive HQ, ensuring your credentials remain private during the strength assessment.
- How accurate are the crack time estimates?
- The estimates are based on industry-standard entropy calculations and assume typical hardware capabilities; actual crack times may vary depending on the attacker's resources and methods.
- What does it mean if my password appears in the breach database check?
- If your password is flagged, it has been found in known compromised databases via Have I Been Pwned; you should immediately replace it with a unique, strong password for that account.
- Can I check multiple passwords at once?
- The tool is designed for single-password assessments; you must enter each password separately to receive individual strength evaluations.
