Learn OAuth with online courses and programs
What is OAuth?
OAuth is an open authorization framework that allows one platform to access resources on a different platform without the need for users to hand over their credentials.Footnote 1 It's billed as a secure alternative to traditional authenticators and works over HTTPS to authorize access to other applications and APIs.
OAuth is commonly used to create a new account on a service, with an existing account from a different platform, and to grant special permissions to a third party. In both cases, OAuth can grant restricted access without your username or password. It keeps user authentication out of the equation to reduce the amount of information exchanged between platforms that can identify you.Footnote 2
OAuth works through access tokens that function like hotel keycards or valet keys; they grant the holder restricted access to do only what's approved from a short list.

How to use OAuth in your career
When you work on a product with functionality that relies heavily on user sign-in, OAuth can be a helpful tool to get them through the door with minimal hassle.
For web developers, software engineers, and anyone whose job involves the construction of digital infrastructure, you can use an open framework like OAuth. It may help in speeding up the development process, so you can focus on other areas of the product. For new products, it can help to give users the option to enter through a trusted service.
If you can build a well-integrated REST API, you can add OAuth to your system and safely hand over many security and data management tasks.
