Managing secured sessions

Do you want your users to log in every time they start the application? Even with Google OAuth support, it can be inconvenient to authenticate repeatedly. To address this and maintain application security, a common approach is to implement sessions.

.NET MAUI provides an API for accessing local secured storage, which can store user-session information. We’ll use this storage to save the access token, allowing access to protected APIs without frequent authentication.

Additionally, we’ll implement token refresh functionality to request a new access token when it expires. We’ll also create a logout feature that removes the token from storage and clears the authorization header from the HttpClient object.
