how do you find wifi network security key?

I'm trying to use iPhone for wifi for my laptop. It asks for network key. Not my 4 digits. I tried apple password. That is not it ??

Tap Settings on the iPhone home screen

Tap Personal Hotspot

Turn on Personal Hotspot

The Wi-FI Password will be displayed

The Wi-Fi Password is the key

Since you do not indicate, I'm guessing it is your network? If so, you are he one that determines it, or it is listed on the device, if you are looking for the short number that is used to auto setup devices to newer networks.

If you are using Apple air port router , open it via spotlight > hold option key and double click on base station .

Take cursor on top menu bar > Base station > click on show passwords .

A window appears you can view wifi network security key .

The OP is not asking for wireless network password or base station password that is 26 - 32 characters maximum ( punctuations , characters , can be numbers all are included in 32 characters ) .

The screen shot shows pre shared key for base station name ( shown with red arrow ) I have hide it for security reason and this lengthy alfa numeric key is auto generated by internet service provider to the user .

The 64 character "key" is not going to help the vast majority of users who can only input a password or passkey of up to about 26-32 characters maximum. Very few wireless devices will allow a 64 character "key" to be typed in.

As you know, none of the Macs or Apple devices will allow any more than 32 characters

Do you have any devices that will allow a 64 character "key" to be typed in? If so, what are they?

We know what the OP was asking for......we were pointing out that what he was asking for very likely would not help him.

Do you know of any WiFi devices that will allow a 64 character input? I don't....that's why I was asking.

The "key" is probably totally useless to you, since it is 64 characters long and very few things will accept an item of this length.

If you have an Apple AirPort router, we can tell you how to find the "key" for the network that it is creating, if you can tell us what operating system your Mac is using.

Most manufacturers use the term "key" to mean the normal wireless network password, which is also known as passkey.

Yes 64 character input is not permissible , its up to 32 characters as to my knowledge .

Thanks for confirming that the 64 character "key" will likely be of no use to the OP.
