I had an argument with an IT professor I know regarding passwords and security. I was mad about my in-laws having a weak WPA1 protected router and the stock password while I insist on having WPA3 and a very strong passphrase.
Well, the discussion continued and later he said something to the point of “everything tries to guess your password, so I don’t have any where it is possible, because the programs don’t know what to do if there isn’t one“
What are your opinions about this?
His statement is that he has no password whatsoever because it is more secure than having a strong password
He’s very, very wrong and there are some good answers above as to the why.
Did he give you an example application where he practices this password-free lifestyle?
Yes and what is the name of his pet?
