I think we must use more modern OAuth2. All above listed websites support it.
Also I suppose add to list LinkedIn. It also has API.

[andrey1s]

what about twitter?

[psdcoder]

Why not)
Now full list looks:

• Google Plus
• Facebook
• Twitter
• LinkedIn
• Vk.com

And maybe we can add authorization through Github. What are you think about it?

[andrey1s]

check the support twitter protocol OAuth 2.0?
