Let's say the application is storing user's phone number so it can send SMS notifications to the user. Encrypt it all you want, but when it is time to send the SMS you will need the phone number in plaintext so you can pass it to the SMS gateway.

Where's the fix?

Thanks, anti-islanding protection must be a fascinating topic. You could look for voltage, frequency, phase anomalies but you also have to balance between being safe and having too many false positives. I'm not sure I'd want to be a line worker knowing there may be many inverters, from various manufacturers and with varying levels of quality, in every direction.
Perhaps a more robust solution would be for the power company to install remote-switchable circuit breakers at various places of the grid. Use some sort of wireless IoT protocol to listen for "on/off" signals and to report back "I'm now on / I'm now off!". Then the power company can disconnect parts of the network by themselves, without trusting that every inverter, generator and battery will do the right thing.

> if they do not see power from the grid, they shutdown
I realize this is a complete noob question but I'm still curious: with enough "backfeeders" could it not in theory be possible that the backeeders see each other's output and keep operating?
Say, a few houses at the end of the line, each with very little electricity consumption (no-one's at home), but with panels and inverters going full tilt, something like that?

I use Yubikeys for WebAuthn 2FA (not as passkeys). Keeping them in sync is not a big issue in practice: I just don't sign up for new services that often. There's a stable set of services I'm using and it is rare that I actively look for something new. Usually it is the other way around--how do I use this thingamajig without creating an account.

It values your privacy in the sense that "it is absolutely worth something so I'mma take it thanks"

But with Cloudflare tunnel (and similar tools), there are no open ports on the origin server.

Do you mean by getting the information from Cloudflare, or some other way? With DynDNS though, finding out my IP is trivial and does not require any special powers or skills, it is just a DNS lookup.
PS. Just re-watched your matrix LED pendant video. It is so well done, both the project, and the accompanying video!

This and Clicks Communicator seem eerily similar.
