What makes a password strong
Length beats complexity
Every extra character multiplies the work to crack it. Sixteen or more random characters puts you out of practical reach — longer beats cleverer.
Never reuse one
One breached site shouldn't unlock ten others. A different password for every account is the whole game — and why a generator matters.
Store it somewhere only you can open
A strong password you can't remember belongs in an encrypted vault — zero-knowledge, so not even the provider can read it.
