Login is the process that allows a registered user to access an account or personalized area of a mobile application by providing credentials or using another authentication method. Depending on the app, users may log in with an email address and password, phone number, social account, biometric authentication, or another supported method.
Login enables a mobile app to recognize individual users and provide access to personalized data, settings, content, bookings, purchases, or other account-specific functionality. It is particularly important for applications that store user information or provide different experiences to different users. A well-designed login process should balance security with a simple and convenient user experience.
A customer opens a booking app and logs in to their account. After authentication, the application displays their upcoming bookings, previous activity, and personalized information associated with their profile.
