Account security is one of the most vital pieces of the busy and interconnected world right now and nobody wants strangers accessing their personal information online. You might use a password manager as well as two-factor authentication like we mentioned in a previous post, but now there’s another way to stay protected.
In response to similar approaches from Google and Dropbox, Facebook has added support for safe login security keys. When you log into your account, this device will prove your identity rather than a code which sends to your phone. In addition to the superior security, they’re also potentially faster. With just a tap on the device you can have access to your Facebook account and feel safer in knowing only you can unlock it. It’s a welcome move from the company in an age where cyberattacks and identity theft are on the rise and as a universal rule on the internet, it’s never a bad time to strengthen your defences.
For those into home-brew programming projects, its easy to make a microcontroller spit out some Morse code with the post shown below. What makes [pavlin’s] take on this project interesting is that it resides on a tiny USB board with an ARM processor. The design for the board is available with single-sided artwork suitable for production using simple methods like toner transfer.
The STM device has a built-in USB bootloader. It can also act as a serial port, which makes the project very simple and a bit more flexible. The only external parts are a speaker and an opt-oisolator.
The program provides a command line interface over the serial port that you can use to program the message and set other options like speed and the delay between messages.
