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?
This is a stupid take. “The programs don’t know what to do” - okay, but people do. This is like not locking your front door at all because you think the lock can be broken. Any lock is better than none. You can set a pass phrase, hide the WiFi SSID, and be done with it. No idea why on earth anyone would just not set any password on a router, or anything for that matter, if there is an option to set one.
