Yes, I agree with you; it is a sign that something is wrong. I have wasted countless hours over the past two years trying to understand how an attacker was getting through to my devices. For months I was getting locked out of my devices because the passcode was not recognized. When I stopped entering the passcode on this screen stating I recently entered my passcode, I stopped getting locked out. Instead of entering the passcode I would force my phone to reboot.
Something else I also noticed is that if my device does not recognize the passcode (that I know is correct) for 3 times I know that I will be locked out the next time my passcode is required. So now when it is not recognized 3 times, I change the passcode once I get back in and then reboot the phone.
Its been 3 months since I have been locked out, which is a record for the past two years.
You might be doing this already, but I suggest you keep a log of issues that come up along with what apps were on your phone and available to data. I have learned a lot about
by keeping these types of notes. Yes, it is extremely time consuming, but it is very helpful in the long run. An example of something I have learned, if your passwords or 2nd factor codes are not recognized when logging into various accounts, another app on the device could be the problem. Also, if you change a password on any account, reboot the device after you change the password, and keep a list of the passwords by date changed. If a password that you know is right doesn't work, try the previous password. This happened to me which led me to start logging out of the account I had just changed the password and then rebooting my device.
I do believe Apple has excellent security, but tech companies are in a battle of their own with hackers. From my experience over the past two years, malicious actors are using system level messages and the vulnerability of other apps against me on Apple devices (Iphone 14, two iphone 13s, SE 3rd generation, and Ipad mini). When I realized I could not escape them, I started analyzing my devices, apps, data, and issues. That is when I started making some progress.
