About Linkedin Sign-in
LinkedIn Sign-in (Sign in with LinkedIn) is an OAuth-based social login service that allows users to authenticate on third-party websites and applications using their LinkedIn credentials. It simplifies the registration and login process by eliminating the need to create a new username and password.
Developers use the LinkedIn Sign-in API to access verified professional profile data such as name, email, and profile picture. It is particularly popular on professional tools, B2B SaaS platforms, job boards, and business-oriented web applications where reaching a professional audience and reducing signup friction are priorities. The service is part of LinkedIn's broader developer platform, now governed by Microsoft.
