If you want to prevent the user from returning to the login activity, there are two approaches:

1. After successful login, the login activity can simply call finish() after starting the main activity. This will end the login activity so when the user presses the back button, the app simply finishes.
2. Have the main activity be the launch activity for the app. In onCreate, you can call startActivityForResult() and launch your login activity. When the login activity finishes, the main activity can either proceed normally if the login was successful, or finish() (or operate in a restricted mode) if the user failed to log in.
