In today's world, where digital privacy has become one of the main concerns of users, messaging apps have also moved towards improving the security of user information. One of the most advanced of these applications is WhatsApp.
In recent years, WhatsApp has introduced new features that have taken user privacy to an unprecedented level; from end-to-end encryption to chat locking and protection against screenshots. In this blog, we will examine these features in detail and their real-world use to protect the content of users' chats.

End-to-End Encryption

End-to-End encryption is the foundation of WhatsApp security. In this technology, messages can only be read by the sender and recipient, and not even WhatsApp itself can access them.

Features:
• Prevent content interception during transmission
• Support for chat, voice and video calls
• No need for manual settings; Enabled by default

⸻

Chat Lock

WhatsApp recently introduced a feature called Chat Lock that allows you to lock specific chats with a fingerprint or password.

Benefits:
• Chats are kept in a separate, secure folder
• Notifications for these chats are displayed without the sender's name
• Personal security for sensitive or private chats

⸻

Prevent screenshots in temporary messages

Temporary messages that are displayed for a limited time (View Once) now come with a feature that prevents screenshots.

Why is it important?
• Content is only seen once
• Cannot be copied or saved
• Suitable for sending sensitive information (e.g. passwords or private photos)

⸻

Privacy control: Who sees what?

WhatsApp now lets you specify exactly who can see:
• Your online status
• Profile photo
• Last Seen
• About me

With the new privacy settings, you can:
• Restrict only specific people from seeing your information
• Define individual settings for each item

⸻

Warning when transferring an account to a new device

To prevent account theft or misuse, WhatsApp sends security warnings and recommends two-step verification when transferring an account to a new phone.

⸻

Two-Step Verification feature

One of the safest ways to protect your information is to enable two-step verification, which requires you to enter the specified password when logging into your account from a new device.

⸻

Use of these features for Iranian users

For Iranian users, for whom the security of their chats, photos, and personal information in the digital space is of great importance, using these features can provide real peace of mind.
Despite filtering, inappropriate control of some platforms, and online abuses, WhatsApp remains one of the safest options for chatting with its advanced privacy features.

Conclusion

With a set of security features including end-to-end encryption, chat locking, screenshot prevention, and detailed privacy settings, WhatsApp has shown that it cares about its users' privacy.
