What are the WiFi passwords that impressed you?

I went to stay in a hotel on business. Before I checked in, I ran to the front desk with my luggage and asked for the hotel's wiFi password. The waitress smiled and said, Look at the wall, "Password: 123456789".

I agreed and went into the room. I can't enter it correctly. If it is wrong, I run to the front desk and ask the receptionist why the password is incorrect. The receptionist confidently told me that you just missed a colon:, and I re-entered: 123456789, and you are connected.

Wi-Fi (pronounced as /wafa/, pronounced as /wifi/ in French), also known as "action hotspot" in Chinese, is a trademark of the manufacturer of the Wi-Fi alliance as a product brand certification, and is a wireless LAN technology created in the IEEE802. 1 1 standard.

Based on the close relationship between the two systems, Wi-Fi is often regarded as synonymous with IEEE 802. 1 1 standard. "Wi-Fi" is often written as "Wifi" or "WiFi", but they are not recognized by the Wi-Fi alliance.

Not every product that conforms to IEEE 802. 1 1 has applied for the certification of the Wi-Fi Alliance, and the relative lack of Wi-Fi certification does not necessarily mean that it is incompatible with Wi-Fi devices.
