Password generator
FreeAvoiding lookalikes drops l, I, O, 0 and 1 — worth it for anything you might read aloud or type from a screen.
Worth knowing
How to get this right.
-
01
Length beats complexity, every time
Adding one character to a password multiplies the search space by the size of the alphabet. Adding a symbol to a short one barely moves it. A 20-character password from lowercase letters alone is far stronger than an 8-character one with every trick applied — and much easier to type.

02
Entropy is the honest measure
The bar above reports bits of entropy rather than a vague word. Under 50 bits is guessable by anyone motivated. Around 75 is fine for ordinary accounts. Past 100 bits you are protected against anything that exists, and the remaining risk is entirely about where you store it.

03
Use a manager, and reuse nothing
A generated password you cannot remember is the point — it means you are storing it rather than reusing one you can recall. The single biggest real-world risk is not a weak password, it is the same decent password across forty sites, one of which gets breached.
