Authenticate youtube account on server

Question

I created a web application which will show all private videos of only one account.

Now I have to authenticate the account to get list videos. I saw 2 ways to authenticate by ClientLogin and Oauth. Which ClientLogin is deprecated and don't know how to use Oauth to authenticate the default account on server.

I have client_id and client_secret for my app.
I try this example but not working and i don't know what in $get['code'] and how can I put username and password of this account when using OAuth not ClientLogin.

Answer 1

It's pretty simple.

You can follow the steps at How do I authorise an app (web or installed) without user intervention? (canonical ?) to get a Refresh Token. At Step 8, choose the YouTube API instead of Drive API. Try to choose the most restrictive scope, eg. readonly. You can embed the Refresh Token (securely!!!!) in your app and then use it at any time to generate an Access Token. Thus the stored Refresh Token behaves like a username/password with restricted permissions.
