What makes a password strong?
Length is the most important factor. A 16-character random password is exponentially stronger than an 8-character one. Using all character types (uppercase, lowercase, numbers, symbols) and avoiding dictionary words, repeated characters, and sequential patterns all increase strength.
What is password entropy?
Entropy measures password unpredictability in bits. Each additional bit doubles the number of possible passwords. A password with 60+ bits of entropy is considered strong. 80+ bits is very strong. Our generator creates passwords with 100+ bits of entropy.
