77.1
Length 12, charset 86 → 77.1 bits
At a glance:The password picks characters from the selected set via a seed-driven pseudo-random sequence; entropy = length × log2(set size).
Formula
charset = chosen mix of lower/upper/digits/symbols
entropy (bits) = length × log2(charset size)
How to Use
- Set length and character sets.
- Enter a seed (same seed → same password).
- Read the password and entropy.
FAQ
Why use a seed?
The seed makes results reproducible; leave it blank for a different password each time (still generated locally).
Is higher entropy better?
Higher entropy means a larger guessing space; aim for at least 60–80 bits.
