1. Set up a complex password and use a two-factor authentication (2FA) for logging in.
2. Make sure all the software is up to date.
3. Install antivirus and anti-malware software and configure it for regular scans.
4. Only use Bluetooth, Wi-Fi, and other network connections when necessary. Avoid transmitting sensitive data over unsecured connections.
5. Securely dispose of your mobile device after it has been decommissioned.
