Russian vote-hacking, and 2FA
So, the Russians had nothing to do with dodgy "signature fails", false announcement of polling places moving, real moving or closing of polling places with little or no notice, "harvesting" of absentee ballots... Good to know American Ingenuity is still a thing, without help from furriners..
As for 2FA, having it actually work might be nice, but as it is, every time I use one of my alternate computers, or a VPN, or use the (horrendous) gmail web interface _on_ my main computer, I get a panic message from Google about a "new device", even if I had had it for years and used it the day before. It's almost like they will not rest until I give up dealing with their buggy IMAP interface on a non-google device, and just turn on the "snoop everything, all the time" stuff in the webmail and app.
But that "no password reuse" advice is "table stakes" for security. But also consider "Don't invite a vampire (IoT) into your home"
