Password Strength Guide

Very Weak (<28 bits) — trivially crackable. Weak (28–35 bits) — not safe. Fair (36–59 bits) — tolerable for low-risk sites. Good (60–127 bits) — safe for most uses. Strong (128+ bits) — recommended for high-value accounts.

Entropy = log₂(charset_size^length). Each extra character adds log₂(charset_size) bits.
