12 or 24 Words in your BIP-39 Wallet? Use a passphrase or not?

On Sep 20, 2018:

If the attacker needs your 24-word seed and your passphrase, that is a good security mechanism. It means that if somebody finds your 24-word seed lying around, you shouldn’t have it lying around, but if they do find it and it’s not sufficiently physically secured, then brute-forcing it, brute forcing the password, will require either a lot of infrastructure or a lot of time. ―Andreas M. Antonopoulos

A relatively complex passphrase will keep you safe for several weeks, a month. A very strong complex passphrase will keep you safe for months; unless the person is willing to spend a million dollars on hardware to break that passphrase. ―Andreas M. Antonopoulos
