How can I make my phone hotspot mode secure?

Episode 1536 (1:40:56)

Mark from Los Angeles, CA
Wi-Fi

Mark wants to use his Android phone as a hotspot. Leo says that it's under the Internet settings under "Hotspot and Tethering." And his phone carrier must support it, usually for an extra charge. But he's having issues using any security with a password. Leo says that's not good. It shouldn't be disabled. Leo wonders if that phone doesn't support WPA2. None is not a good choice. If there's WEP, that wouldn't be great, but it's better than nothing. He'll ideally want WPA2 with PSK (pre shared key).
