A guy at a coffee shop in Portland showed me how easy it is to grab public wifi data

I was working at a cafe last month and this guy at the next table just started talking to me. He pointed at my laptop and said, 'You know, I can see every site you're visiting right now, right?' He wasn't being creepy, just showing me something. He opened his own laptop and in about 2 minutes, using a free tool called Wireshark, he pulled up a list of the unencrypted traffic from the cafe's network. It had my login page for a news site, plain as day. He said, 'If you're not using a VPN on public wifi, you're basically reading your mail out loud.' It was a real wake-up call. I bought a VPN subscription that same afternoon. Has anyone else had a moment like that that made them change a habit fast?

My old bank used to text me codes for login, and I thought that was super safe. Then a friend at a tech meetup in Austin asked if I ever got a new SIM card, because that's an easy way for someone to steal those codes. I switched to an authenticator app the next day and felt like I'd been using a screen door for a lock. Public wifi is just one piece of the puzzle.

Guess I've been shouting my passwords for years, huh?

Oh man, that hits home. I used my dog's name for everything until I saw my own Instagram post wishing him happy birthday with his full name and my birth year. Felt like I mailed my house key to a thief. Now my password is just a random sentence about the weather. What's your go-to bad password habit you had to break?
