That would be a game-changer for so many people. We're already getting close, though. Those CGMs like Dexcom don't actually test blood; they check interstitial fluid. There's a 5-15 minute delay, but still way better than finger pricks all day.
Non-invasive monitoring is still tricky. There’ve been some interesting attempts—like GlucoWatch back in the early 2000s, which used mild electrical currents, but caused skin irritation and never really caught on. Others have tried optical monitoring, radio waves, ultrasound, and even heat-based sensors. Feels like we’re getting closer, just not quite there yet.
A similar idea appears in a more recent short story, How It Unfolds (2023) by James S.A. Corey. The premise is using a technology called “slow light,” which can clone people and objects using “enriched light.” The National Space Agency scans a group of 200 people (not only their physical forms, but also their consciousness, memories, and feelings) and transmits several thousand copies of this data package across the galaxy. The hope is that, on arrival, each package can "unfold" into a fully reconstructed version of the original team and habitat on some distant alien world.
Some users chose Authy precisely because of the desktop app. Phones can be lost / stolen / unresponsive / out of battery, and it was nice to have a second option for 2FA.

> Please be aware that Twilio Authy does not have any affiliation with the companies creating these apps, so be mindful of potential risks and exercise your own judgment when selecting the app.
> Note: The Authy app lacks an export feature, therefore you have to re-enable the 2FA method and re-add the token in your new application with the steps here.
