Duo vs WhatsApp: What are the differences?

Introduction: Duo and WhatsApp are both popular communication platforms that offer various features for connecting with others. However, they have key differences that set them apart from each other.

1. End-to-end Encryption: One of the main differences between Duo and WhatsApp is the approach to encryption. While both platforms offer end-to-end encryption for calls and messages, WhatsApp encrypts all communication by default. On the other hand, users need to enable end-to-end encryption on Duo, making it an opt-in feature.

2. Contact Connectivity: WhatsApp requires users to have a phone number to register for the service, allowing them to connect with others based on their contacts' phone numbers. In contrast, Duo does not require a phone number for registration and instead uses email addresses or Google accounts to connect users.

3. Group Calling Features: WhatsApp allows users to make group video and voice calls with up to 8 participants, making it a convenient option for small group conversations. In comparison, Duo offers group calling with up to 32 participants, providing a larger capacity for group video calls.

4. Integration with Other Apps: WhatsApp offers integration with various third-party apps, allowing users to share content from other platforms directly within the chat. Duo, on the other hand, does not have the same level of integration with external apps, focusing primarily on video calling features.

5. File Sharing Capabilities: WhatsApp allows users to share a wide range of file types, including documents, images, videos, and audio files, making it a versatile platform for communication. In contrast, Duo is primarily focused on video calling and does not have extensive file sharing capabilities beyond sharing images during calls.

In Summary, Duo and WhatsApp differ in their approach to encryption, contact connectivity, group calling features, integration with other apps, and file sharing capabilities.
