To add on, at my work we started getting yubikeys for the people who didnt want Microsoft’s authenticator on their phone and found they still need to download the mfa to set up the yubikey in the first place. So its not a perfect solution if you dont want the authenticator to touch your phone at all.

I can also confirm that the help desk members who are not enlightened about Microsoft will ridicule you for not wanting the MFA even if its reasonable to not want Microsoft on your phone. As much as we think all techs are Linux nerds, I have the opposite at my work. Some of the higher up techs are constantly trying to get people to switch to windows 11…

While animals can hear different frequencies, the researchers talked about editing the audio for volume and such. I would assume these scientists, who are already concerned about the audio content/volume, would think about that. All they would need to do is take the clips, put them a spectral analyzer and eliminate any frequencies outside of the range of frequencies the animal making the sound could make. So it would be rather trivial for them to do. Youre also assuming the speakers could reproduce that static but if they’re tuned for human hearing ranges and not really cheap speakers then the chance of some elephant scaring static is low.
