A: 1. Our company only allows individual accounts with merged account to activate the quick login function. If you have applied for the iPost, log in to the Post APP with your ID number, username, and password. After logging in, the system will guide you through the setup process. You can enable quick login as prompted on the screen. The next time you log in, you can log in to the Post APP through the built-in face, fingerprint or self-set graphic password of the mobile device without entering the "username" and "password".
2. For individual customers who meet the conditions for logging in with their ID number but have not yet changed to using their ID number for login, you can enable the quick login service after changing to login with ID number on Post APP. If you haven't applied for the iPost service yet, please refer to "Q: How do I apply for logging in to the Post APP?".

A: 1. The mobile device must be set up with a screen lock function, such as fingerprint/face or iris recognition, pattern lock or numeric password, etc., in order to use quick login. If your device has not been set up with a screen lock function, or can be unlocked by simply "sliding", it will be restricted by security control specifications and cannot use the quick login.
2. For individual accounts logged in with an account number, if it is a merged account, you can log in to the APP and follow the guide to switch to ID login, and then set up quick login.

A: Due to the system's inability to restore the quick login feature of the APP directly through backup, if you transfer the Post APP to a new mobile device by directly backing it up, you may encounter a message indicating an abnormality in quick login verification. In this case, we suggest that you try deleting the APP, downloading it again, and then setting up the quick login feature.

If you encounter this message, it could be due to one of the following three situations:
1. The Post APP encountered data abnormalities due to using the backup method to transfer from an old device to a new one. Please try uninstalling the app and then downloading and reinstalling it.
2. If you encountered this issue after updating the Google Play Store, you can try the following steps:
(1) Find the Google Play Store app on your device's home or app screen.
(2) Touch and hold the Google Play Store app.
(3) Tap App info.
(4) Tap Storage & cache and then Clear Cache.
(5) Tap Clear Storage and then Delete.
3. If your Android device did not come with Google services pre-installed and you installed the Play Store through unofficial means, it might not be Play Protect certified, and as a result, you might not be able to use the Post APP.

A: 1. For transaction security, if the mobile device has been jailbroken (JB/ROOT), it will not be able to use device authentication related services and must be factory reset then it can be used.
2. If USB debugging mode is already turned on, you can follow the steps below to turn it off (the names of each option will vary depending on the brand and version of the mobile device):
(1) Open the phone's "Settings".
(2) About Phone > Version Information > Tap "Version Number" 7 times in a row > "You are now a developer" appears.
(3) Go back to "Settings" > Other Settings > Developer Options > Turn off "USB Debugging".

1.This message usually means that your device can't download the Post APP from the Google Play Store because it isn't Play Protect certified.
To fix the problem:

(1)Open the Play Store app.
(2)In the upper right, tap your Profile icon.

(4)Under Play Protect certification, check your device's certification status.
