Frequently Asked Questions
How secure are the generated passwords?
Our password generator uses cryptographically secure random number generation to create truly random passwords. The strength depends on the length and character types you select.
What is password entropy?
Password entropy measures the randomness and unpredictability of a password. Higher entropy (60+ bits) indicates a very strong password that's difficult to crack.
How often should I change my passwords?
Security experts recommend changing passwords every 3-6 months for sensitive accounts, or immediately if you suspect a breach.
Should I use password managers?
Yes! Password managers securely store unique passwords for all your accounts and can generate strong passwords automatically.
