The sequence of steps a user takes to complete a specific task within a system.
Description
In the context of Single Sign-On (SSO) protocols, user flow refers to the pathway that a user follows to authenticate their identity across multiple applications using a single set of credentials. This process typically begins when a user attempts to access a service that requires authentication. Instead of creating a new account or logging in separately for each application, the user is redirected to a centralized authentication server. Here, they enter their credentials, which are then verified. Upon successful authentication, the user is redirected back to the original service with an authentication token that grants them access without needing to log in again. This streamlined process enhances user experience by reducing the number of login prompts and passwords users need to remember, thereby improving security and convenience. User flow is crucial in SSO design, as it affects user satisfaction and the overall efficiency of the authentication process.
Examples
- Google's SSO allows users to access Gmail, YouTube, and Google Drive with one login.
- Facebook Login enables users to sign into third-party apps like Spotify without creating a new account.
Additional Information
- A well-designed user flow minimizes friction and encourages users to engage more with the services.
- Tracking user flow can help developers identify potential barriers in the authentication process.
