Google: Add account to other device login notification function
The online world is becoming more and more dangerous. Once Google accounts with various types of personal data are stolen, the consequences are even more unimaginable. To promptly let the account owner know that the account has been accessed by unknown persons, Google adds a notification mechanism to the latest Android system. After the Google account is successfully logged on, if you have logged on to an Android device, a notification is displayed, indicating that a new device has been logged on to your account. Real-time notifications allow users to change their passwords and log out of all devices in a timely manner, reducing the damage caused by hackers.
New features will be pushed to Android devices one after another. It may take about two weeks for some friends to receive the new features. In any case, the security enhancement measures are always better late than never.
