“It will take longer to be broken, forced. There is also statistically less risk of a complex phrase ending up in an already existing list of passwords. So indeed, it will be more secure.”, says Gianino Cuignet, Director of Security Services at Redsystem. “The long phrase, it’s easy to remember, we can set up a mnemonic device to remember it. So, maybe a phrase of the same length or a random password of the same length, with characters specials, will be even stronger. But on the other hand, to retain them, it will become much more complicated. So the sentence as it stands does the job rather well.
Yes, because for example: P]8gT8Pv/(5!E7v3fDt, it’s obviously a great password. But if it’s to forget it, or worse, have to write it down somewhere, it’s useless!
