Default SSID and WLAN password: Scan the QR code.
It will show something like WIFI:S:PXC5.E003_0000550;T:WPA;P:1400052738;;
Then SSID = PXC5.E003_0000550 and password = 1400052738

Determine manually: Use the information from the Date/Series/SN block It will show something like:

Date/Series: 20190423A0000550
S/N: 1400052738

SSID = <ASN>_<Running number after the series letter> and password = <S/N>
