Entropy & strength
entropy (bits)How unpredictable the secret is — higher is exponentially harder to guess. Length × log₂(character pool), or words × log₂(list size).~60 bitsA sensible floor for important accounts. Below ~36 bits is weak; ~128 bits is overkill-strong.length winsAdding length raises entropy faster than adding exotic symbols. A long passphrase beats a short cryptic password.Passwords vs passphrases
passwordRandom characters from the pools you enable. Compact and high-entropy, but hard to memorise — use a password manager.passphraseSeveral random words joined by a separator. Longer but far easier to remember and type; great for a master password.no look-alikesDrops confusable glyphs (I l 1 O 0) so a written-down secret is unambiguous — at a small cost to entropy.
