WiFi Network 94f22a is an open network.
WiFi Network ea9952 is password-protected.

Note: a person using your open network will not have access to your computer or files - it simply means that they can access the internet and possibly download files to their own computer. Sometimes it is convenient and generous to have an open network, such as a coffee cafe, library or hospitality area. The only danger might be if it were used for nefarious purposes (terrorism, pornography, drug orders etc) - the ISP address of the network's owner would be trackable by authorities.
