常见问题
What is entropy?
Password unpredictability in bits; 80+ bits resists offline brute force for decades.
Length or complexity?
Length wins: each extra character multiplies combinations by the pool size.
Avoid ambiguous characters?
Skipping Il1O0 prevents mistyping when reading passwords aloud or from print.
