Best Practices for Integrating OAuth in Mobile Applications for Secure Authentication

For safe authentication in mobile apps, OAuth is becoming the de facto standard. Strong and reliable authentication methods are more important than ever before due to the meteoric surge in mobile app use. This need is satisfied by OAuth, which allows for protected resource access while protecting user credentials from prying eyes in third-party apps. In order to guarantee security and a smooth user experience, this abstract details best practices for incorporating OAuth into mobile applications, with an emphasis on critical concerns and tactics. An overview of OAuth's fundamental concepts, such as its authorisation processes, token management, and scope definitions, is provided at the outset of the talk. Use cases include mobile apps that make use of the Authorisation Code Flow with Proof Key for Code Exchange (PKCE) highlight the need of selecting the appropriate OAuth flow. Here is some practical advice on how to put these ideas into practice: make sure the OAuth client is securely registered with the authorisation server, use the device's secure storage facilities to store tokens, and use the right techniques for token expiry and renewal.
