WhatsApp is set to make contact management more secure and convenient by introducing an in-app contact-saving feature. With this update, users can save contacts directly within WhatsApp, ensuring they’re accessible across devices without relying on the phone’s address book. Contacts will now be stored in WhatsApp’s cloud storage, maintaining accessibility even if users switch devices or lose their phones, a notable shift from the previous phone-syncing approach.
How the Feature Works
- Save Contacts Directly in WhatsApp: Users can now add contacts within the WhatsApp app, which will be stored in the cloud. This eliminates the need for syncing with the device’s address book, allowing for seamless management across WhatsApp Web, Windows desktop app, and mobile.
- Encryption for Enhanced Security: WhatsApp has introduced a new encryption protocol called Identity Proof Linked Storage (IPLS). When a contact is saved, a unique encryption key is generated on the user’s device, ensuring only authenticated devices can access or retrieve the information. WhatsApp has also collaborated with Cloudflare to verify cryptographic properties, preventing unauthorized changes to contact lists.
- Sync Option for Traditional Users: For those who prefer integration with their device’s contacts, WhatsApp offers an option to sync saved contacts back to the phone’s address book, catering to both preferences.
- Cross-Device Compatibility: The contact-saving feature will function across WhatsApp Web and desktop apps, allowing users to manage contacts from any device without depending on the primary mobile device.
WhatsApp’s Ongoing Account Management Improvements
This feature follows WhatsApp’s recent enhancements in account management, including multi-account support on one device, ideal for keeping personal and professional contacts separate. Now, with in-app contact saving, users benefit from an organized, device-linked contact list that remains independent of phone storage.
Looking Ahead: Username-Based Contact Saving
WhatsApp plans to introduce username-based contact saving to improve privacy further. This feature would enable users to share usernames instead of phone numbers, aligning WhatsApp with privacy-focused competitors like Signal and Telegram. By using usernames, users can connect without compromising personal contact information, adding an extra layer of security to online interactions.
