Protect Your Privacy, Be extremely cautious with your personal information. Never disclose sensitive data to anyone claiming to be from the casino, as this could be a ploy to steal your funds or identity. Legitimate casinos won't ask for this information upfront.
For those of us who may not like to access the casino through their website but via their mobile app, the caution for you here is to ensure you are using secure casino apps downloaded from reputable sources like the Apple Store or Play Store. Furthermore, make sure your network connection is via a secure Wi-Fi network. I do not advice you to use a public or shared networks due to the security risks it posses. Using mobile data or a secure home Wi-Fi connection is advised.
I prefer to access the casino using the browser on my device rather than downloading the application because I think it is safer for gambling and takes up less space on my device. But if they want to use the casino app, they should always be careful before installing the app and download the app from the casino directly so that there are no problems later. Also, ensure your internet connection by not connecting to the internet in public places which may be prone to hacking cases.
