WhatsApp, the popular global messaging app, offers end-to-end encryption for every chat, ensuring that only you and the person you're communicating with can access your exchanged messages. However, a lesser known but essential security aspect is the unique security number assigned to each chat.
WhatsApp says this may change with changing devices or reinstalling the app. So, enabling security notifications is a crucial step to always be aware of the integrity of your conversations.
Enabling security notifications in WhatsApp
To enable these notifications, navigate to the WhatsApp settings, go to the "Account" section and then "Security". Here you will find the option to enable security notifications. Once activated, you will be immediately notified of any changes to your contacts' security number, ensuring total transparency and increased security.
Optimizing voice messages
WhatsApp offers a number of tricks to optimize and customize the user experience. For example, to listen to a voice message before sending it, simply press and hold the microphone icon, then swipe up to block recording.
This allows you to record your message without holding your finger on the screen, and by pressing the pause button, you'll be able to listen to the recording before deciding whether to send it or record a new version.
Customize notifications and wallpaper
Another valuable aspect of WhatsApp is the ability to customize notification sounds for different contacts. This can help you quickly identify who sent you a message without checking your phone. To set a different notification sound, select a chat, go to the contact information and choose "Custom notifications" (Android) or "Wallpaper and sound" (iOS), where you can choose a different tone for each contact.
Personalization goes even further with the ability to set different background images for each chat. This adds an extra level of personalization, giving each contact a unique look. On Android, this option is found under the three-dot button in the chat menu, while on iOS, select "Wallpaper and sound" from the contact or group information.
WhatsApp through these features not only increases the security and integrity of conversations, but also offers a more pleasant and personalized user experience. By enabling security notifications, customizing notifications and wallpapers, WhatsApp becomes a safer space closer to the individual needs of each user.
In a digital landscape where security and personalization are key, these features are essential for any WhatsApp user aware of the importance of privacy and personal expression.
