How to Calculate Password Generator
What is Password Generator?
A password generator creates random passwords with specified length and character types. Password strength is measured in bits of entropy: a password with entropy N bits would take 2^N guesses to crack by brute force.
Step-by-Step Guide
- 1Entropy = log₂(charset size^length) = length × log₂(charset size)
- 2Lowercase only (26): 8 chars = 37.6 bits
- 3Mixed case + digits (62): 12 chars = 71.4 bits
- 4All printable ASCII (95): 16 chars = 104.9 bits — very strong
Worked Examples
Input
16 characters · mixed case · numbers · symbols
Result
e.g. "xK#9mP$2nQ@7rL!4"
