WhatsApp is testing a new feature that will allow users to sign in using a username instead of a phone number for increased privacy.
The new beta version of WhatsApp includes the option to create usernames, but the feature is still in the early development stages.
There are specific rules for WhatsApp usernames, such as not starting with 'www' and restrictions on symbols and length.
Recent updates to WhatsApp also include fixes for privacy leaks, new features like voice chat in group conversations, AI wallpapers, and message summarization.
