Boffins convert typing sounds into text with 95% accuracy (www.theregister.com)

Researchers in the UK claim to have translated the sound of laptop keystrokes into their corresponding letters with 95 percent accuracy in some cases.

That 95 percent figure was achieved with nothing but a nearby iPhone. Remote methods are just as dangerous: over Zoom, the accuracy of recorded keystrokes only dropped to 93 percent, while Skype calls were still 91.7 percent accurate.

In other words, this is a side channel attack with considerable accuracy, minimal technical requirements, and a ubiquitous data exfiltration point: Microphones, which are everywhere from our laptops, to our wrists, to the very rooms we work in.

Only if you have to type it in to unlock your vault. Now, bear with me.

Bitwarden (maybe others) lets you set a PIN to unlock your vault. Normally, you would think this is a less secure setup, easier to crack with the method outlined in this article. Except with Bitwarden you have to set up the pin in every browser extension and every app install.

Meaning, unless they have access to your device, the PIN to unlock one instance of Bitwarden could be different from the PIN for another. They also don't have to be strictly 4-digit PINs, either. I highly recommend password managers, but for my money, Bitwarden has all my love.

Disclaimer: I am on no way affiliated with Bitwarden. But I could be if they paid me!

but then I have to remember the PIN for each one of my devices. there should be some kind of app for storing those.

Do what users at most businesses do, write it on a sticky note and put it on the underside of your keyboard!
