Prompt: “This is not a valid code”

Description:

This error usually appears when the time on your device is not synchronized correctly. The authenticator app relies on your device clock to generate accurate security codes, so even a small time difference can cause invalid codes.

Step-by-Step Solution

1. For iPhone Users:

  1. Open Settings → General → Date & Time.

  2. Make sure “Set Automatically” is turned ON.

  3. To force sync the time:

    • Turn “Set Automatically” OFF for a few seconds.

    • Then turn it back ON.

2. For Android Users:

  1. Open Settings → System (or General Management) → Date & Time.

  2. Ensure the following are enabled:

    • Use network-provided time

    • Use network-provided time zone
      (On some devices, these may appear as “Automatic time” and “Automatic time zone.”)

  3. To force sync:

    • Turn these options OFF for a few seconds.

    • Then turn them back ON.


After Fixing the Time Settings:

  • Reopen your Authenticator app.

  • Try generating and entering a new code again.

If the issue persists, double-check that your device time zone matches your current location and that your device has an active internet connection.
