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.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.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.

Explore jobs that use OAuth

Knowledge of OAuth can come in handy in a variety of professional roles, such as:

  • Web developer: These professionals tend to be in charge of the construction of server-side architecture.3 Web developer jobs include back-end and full-stack roles.

  • Software engineer: These professionals write code for a platform, mobile or desktop applications, or other services that can integrate an authorization service to make user credential management easier.4

  • Identity and access management (IAM) specialist: These professionals manage system access for the company's personnel (e.g. by seniority levels or departments).5 In this field, you can be a manager or analyst.

  • Enterprise architect: These professionals oversee the design and implementation of business systems, both in hardware and software, which includes cybersecurity.6

In any of these roles, it may be useful to familiarize yourself with the technology used to power OAuth. One way to do this could be enrolling in a coding boot camp. For example, the study of how Javascript frameworks integrate OAuth is important for web developers. If you’re more interested in cybersecurity OAuth jobs, a cybersecurity boot camp might be more appropriate. Before deciding on a specific learning path, research potential roles you hope to pursue and align your coursework with your professional aspirations.

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.
