If you suspect someone else is reading your WhatsApp messages, you can check and remove unauthorized access.
Go to the 'Linked Devices' option by clicking on the three dots in the top right corner.
This will display a list of devices connected to your account.
If you see any unfamiliar devices, remove them to protect your account.
WhatsApp also recently introduced a group context card feature, providing detailed information about group creators and members, helping users decide whether to stay in or leave groups.
