A. 1. Use a password manager: Consider using a password manager app to store your passwords and payment information securely, making it easier to log in and make purchases. 2. Manually enter information: If the app does not support saved passwords, you may need to enter your login and payment information each time you use the app.

B. 3. Check for updates: Ensure you have the latest version of WienMobil, as updates may improve integration features.
