Iphone and ipads will not recognize fingerprint and to unlock it requires keyed passcode to open
I have 2 iPads, 1 iPhone 7 Plus and a 2017 27” iMac. I recently started using the fingerprint to unlock feature which is very nice, if it works. What happens is I will set it up using a certain finger and once I go through all required steps it tells me it has been completed. So I lock the device so I can use the fingerprint and it usually works. Now after using and then laying it down when I’m done. Now the next time I pick it up to use it I use the same finger to unlock but it won’t allow me to and it says to use keyboard to key in code. now this has happened numerous times and so I did a little research and checked all the reasons why Apple says it may be doing that. The last thing I tried was registering the same finger 3 times. It worked for the first time or two but after I quit using the device and I lay it down the same thing happened when I picked it up to use it again.
this is happening on my 2 iPads and my iPhone.
Now I have been told that that behavior could be a sign of a hacker or malware. Could someone please help me figure out how to use these features properly. Also, if someone could point me into a direction where I could have a tech go through and look at my computer and devices and tell me if in fact someone has hacked my other devises? I am concerned that someone has indeed been able to get into my internet, my computer, iPhone, iPads and wyze cameras.
thanks
