WhatsApp has started testing a new feature that will allow users to easily mention all members of a group chat in one go. The feature is being rolled out as part of the latest WhatsApp beta for Android (version 2.25.32.9) and is currently available to some beta testers via the Google Play Store.
This feature was previously spotted in development and now appears within the mentions menu. By using this new shortcut, users will be able to alert every member of the group, ensuring that important messages don’t go unnoticed—even if members have muted group notifications.
WhatsApp is reportedly also testing another setting that will allow users to mute @all mentions, giving them better control—especially useful for those who are part of multiple active groups. This will help users stay informed about significant messages without being overwhelmed by constant notifications and updates. This command is being developed to enhance communication within large groups, where messages often get lost amid high activity.
It will be particularly useful in professional teams, communities, and families that need to share important information efficiently. According to WABetaInfo, in small groups, every participant will be able to use the @all feature. However, in groups with more than 32 participants, only admins will have access to this functionality.
Another report from WABetaInfo suggests that WhatsApp could soon introduce the option for users to reserve their usernames ahead of the official rollout. This means individuals may soon be able to choose a personalised username of their choice, potentially eliminating the need to share their phone number for messaging. The WhatsApp username feature is still in the development phase, but reports indicate it could become available in the near future.
Once the WhatsApp username reservation system goes live, it is expected to provide a more private and streamlined way of communicating. The feature is currently visible in the WhatsApp beta testing programme on the Google Play Store.
Every username on WhatsApp will have to be unique, ensuring that no two users share the same identity. If a username is already in use, the app will alert the user and prompt them to select or modify their choice accordingly.
In addition to usernames, WhatsApp is said to be working on an extra layer of security known as a “username key”. This key could function as a short password or code, which would need to be entered correctly by anyone attempting to start a chat. This means only those who know the key can initiate contact, preventing unsolicited messages and adding a layer of protection for users’ privacy.
