Hi, I am trying out the NimBLE_Secure_Server example and it did work.

What is the setting that is need for the BLEServer to present passkey Input dialog before ability to access the Services and Characteristic? I am using nRF Connect on Android phone. Thank you.

The lines you'll want are:

NimBLEDevice::setSecurityIOCap(BLE_HS_IO_DISPLAY_ONLY); // use passkey
NimBLEDevice::setSecurityAuth(false, true, true);
