WhatsApp Security Features: Millions use WhatsApp for interacting with their family and friends. The platform recognizes the importance of chats and offers the ability to save chat history on Google Drive. The automated backup feature allows users to choose from daily, weekly or monthly backups of their chats. This is all you need about its security features.
WhatsApp Security Features
Last Seen:
The Last Seen function is one of the most used security features. It allows users to see when they last saw messages.
End-to-End Encryption:
This option has created a new method for storing encryption keys. It works on both iOS AND Android. Backups with E2EE backups enabled will be encrypted using a unique, random-generated encryption key.
Two-step Verification:

Two-factor authentication (also known as 2FA) is a feature that should be used by all services. This adds a passcode on a daily basis and protects your data against unauthorised access.
Go to Menu > Settings > Account > 2FA > Check the box. You can create a 6-digit PIN code that is easy to remember .
Important: Make sure to include your email address in order to get the code back if it gets lost.
WhatsApp does not offer complete security, despite all these advantages. You can use other, more secure communication programs instead. Its security protocols should be sufficient for 99 per cent of users. To avoid security problems, make sure that you regularly update it.
