Find your forgotten wifi password, to which your machine is connected.

Currently this post is only limited to mac, because I don't have access to any other OS machine.

There are two way that can be done

1. Keychain Access
2. Command line

Keychain Access

• Open your keychain access. 
• Spotlight search (Cmd+Space)
• Search "Keychain Access"
• In top right corner search your wifi-connection name. I have used "BankerTech" wifi-connection name in example.

Searching wifi-connection name in Keychain Access

• Double click your wifi-connection name.
• New small window will appear, click show password
• It may ask for login password.

Show password screen, where you will actually see the password in plain text

Command line

• There is a simple command to do the same in terminal
• Start terminal. Spotlight (Cmd+Space), search Terminal.
• Type 
• security find-generic-password -ga "BankerTech" or
• security find-generic-password -ga "BankerTech" | grep password
• replace "BankerTech" with your wifi-connection name.
