Frequently Asked Questions
What is password entropy?
Password entropy measures the randomness and unpredictability of a password. Higher entropy means stronger security against brute force attacks.
How is crack time calculated?
Crack time estimates how long it would take to guess a password using modern computing power, based on password entropy and character set size.
Why should I use a password manager?
Password managers securely store unique, complex passwords for each account, reducing risk from password reuse and making security manageable.
Are password generators truly random?
Modern password generators use cryptographically secure random number generators, making passwords unpredictable and secure against attacks.
