What methods can be used to ensure the accuracy of the device time and prevent any tampering with it? I am seeking ways to implement this feature on both Android and iOS devices

After conducting some research, I've come up with a few thoughts on this issue.

  1. One approach is to implement custom logic to verify the accuracy of the device time (I am using Firebase for backend).
  2. Another option is to check if the device's Automatic date & time update setting is enabled and prompt the user to enable it if not.

I believe that the second option would be more effective in addressing this particular issue. I would appreciate any guidance or code examples for implementing this in React Native version 0.62.2. If you have any other suggestions or solutions to resolve this issue, please feel free to share them. Thank you.

Answer №1

In order to ensure accurate device time, it is important to compare the device's time with the server's time. Firebase Cloud Firestore offers access to the current UTC timestamp, allowing you to cross-reference the device milliseconds with Firestore timestamp milliseconds for verification.
