  • Never enter or send sensitive or confidential information while on public wi-fi (e.g., entering passwords, inputting credit card information, etc.)
  • If you send sensitive information via text message, be sure to use secure messaging apps such as Signal or WhatsApp. Using these apps will encrypt your messages.
  • Be mindful of where you view sensitive information. If you’re in a public location where people can look over your shoulder, avoid viewing sensitive or confidential information.
  • Be cautious when connecting your phone via Bluetooth or USB to a rental car as information may be stored onto the cars entertainment system.
  • Be sure to only download legitimate apps from well known, trusted app stores.
    • Check for ample reviews of app
    • Beware of apps asking for unnecessary permissions
