Questions are raised by the security of the tag because it can be used to secretly spy on someone: for example, discreetly put a gadget in the bag of your partner or competitor and always be aware of where it is and where it goes/goes.
The way AirTag warns passers-by about a lost tracker nearby can help to some extent: it makes a sound after three days of loss. But if you live with a person who is following you, AirTag will not beep, as it will see the “parent” device every day.
To combat this problem, a new tracker update is aimed, which should “prevent unwanted tracking.” Now AirTag will beep not after 3 days, but during time windows from 8 to 24 hours. If someone discovers an unwanted device, just bring an iPhone or gadget with NFC to it and get instructions on how to turn off tracking.
In addition, CNET reports that Apple is working on an Android app to detect AirTag, with the company promising to share more details “later this year.”
In terms of firmware, AirTag will automatically update when you are near the iPhone.
