Here trivial means that it shouldn’t appear in a dictionary so it will reddit the first million most probably password attack, the crypto techniques will take care of the rest to make them un feasible

With bcrypt + round parameters, password stretching or any other key derivation technique, even weak passwords cant be cracked in a realistic time frame
