Seems like this is recommending the use of 8 character passwords... Even with upper/lower case letters, numbers, and special characters can't an 8 character password technically still be brute forced in like 10 minutes?
Yes, if you were using this as a key for a encrypted vaults with nuclear secrets, 8 wouldn't be sufficient.
But if your using this with online services that implement rate limiting, (or TPM, or Hardware security key), the rate limiting makes this sufficiently complex.
So Bitwarden (rate limiting), hardware security key (something you have), and knowing how to read your password card (something you know). Gets you pretty far in terms of usable security.
Nothing is stopping you from using 16, 32, 64 characters, you just have to come up with a system you like to read the card
Fair enough, all good points! Assuming you are using the 8 character columns as unique passwords, I guess this also promotes the use of different passwords for different accounts which is also a good practice!
