OAUTH2

The Problem

I’m a web app that wants to allow other web apps access to my users’ information, but I want to ensure that the user says it’s ok.

The Solution

I can’t trust the other web apps, so I must interact with my users directly. I’ll let them know that the other app is trying to get their info, and ask whether they want to grant that permission. Oauth defines a way to initiate that permission verification from the other app’s site so that the user experience is smooth. If the user grants permission, I issue an AuthToken to the other app which it can use to make requests for that user's info.

Note on encryption

Oauth2 has nothing to do with encryption -- it relies upon SSL to keep things (like the client app’s shared_secret) secure.

Standards And Validation

• Check your code: Remember to validate your code
• Validate that all of your forms are working: Check any automatic emails for spelling mistakes and that it looks good on all email clients. Also, it's a great idea to add a link to social networks on all of your touchpoints.

Website SEO

• Check your keywords: Ensure you have your meta description in place, and that any keywords are suitable for the site
• Check your titles: A popular structure for page titles is: Name of my page | websitename
