What is Password Generator?
Strong, unique passwords are the foundation of online security. A good password should be long, random, and contain a mix of characters. This generator creates cryptographically secure passwords that would take millions of years to crack with current technology. Never reuse passwords across different accounts — use a password manager to store them safely.

Frequently asked questions
How long should a password be?
Security experts recommend a minimum of 12 characters, with 16 or more being ideal. Each additional character exponentially increases the time needed to crack the password. A 12-character password with mixed characters would take approximately 200 years to brute-force with current technology.
Are randomly generated passwords really necessary?
Yes. Humans are predictable when creating passwords — we use common words, dates, and patterns that attackers know to try first. Dictionary attacks can crack common passwords in seconds. Randomly generated passwords eliminate these patterns and provide true security against automated attacks.
Should I include special characters in my password?
Including special characters increases the character set from 62 (letters + numbers) to 95+, making passwords significantly harder to crack. However, length is more important than complexity. A 16-character password using only letters and numbers is stronger than an 8-character password with special characters.
