I don't know if there any genuine video tutorial that explained how to sign in a message using metamask but you don't need any credentials like a password to do the sign message so I will advise you to discard the information provided in the video you watch and below is the process.
1) Just go to
https://www.myetherwallet.com/2) Click
"Access my Wallet"
3) Choose the
"Mew CX"
4) Log your wallet through Metamask by Accept terms and Click
"Access My Wallet" button but you'll to accept the request on Metamask through a pop-up window request..
5) Now you have signed your wallet on the Mew site using metamask, click the
"message" link
6) Write the message want to sign in with an example is showing in the pic and click
"sign" 
7) another pop-up window will show on Metamask requesting your signature to complete the process, click the
sign shown on the Metamask and confirm the signing message on the mew site then you have your complete the process.
Copy it and send it to the person that requests it.
