Estimate how long it would take to crack a password using modern hardware. The result is based on entropy, character variety, and current attack assumptionsy, and current attack assumptions.
Understand how password strength is estimated and why longer passwords are more resilient are more resilient.
These estimates assume an attacker tries candidate passwords at a given rate, using the average position in the search space. Faster computers shorten the timeline, but stronger passwords still remain secure for years or longer.
Our estimates use realistic modern hardware assumptions. GPU-based attacks can be much faster, but a high-entropy password still offers strongfers strong protection.
A password that could be cracked in hours is clearly weak. One that would take years or centuries to break offers much stronger protection, assuming the password is stored securely and not exposed in a breach.
Always use a unique password for every account. That limits the damage if one service is compromised, regardless of how long a single password might take to crack a single password might take to crack.
Every extra character increases cracking difficulty dramatically because of entropy growth. In practice, length is often more important than complexity. Use our password generator to create long passwords, then verify themcalculator and character set analyzer.

Common questions about password crack time estimates.
Yes. These estimates use realistic brute-force assumptions, but actual results can vary depending on hardware, defense measures, and whether the password is exposed in a breach
Generate a new password with our password generator and aim for 16 or more characters using a mix of character types. That can increase crack time from hours to centuries or more.
Yes. Length is usually the most important factor for security. A 20-character lowercase password is often stronger than a 10-character password that uses many differentrent character types.
