Overview
- Admins or group members can choose to send 25, 50, 75 or up to 100 recent messages to someone who is added to a group.
- Reports indicate the default selection can include up to 100 messages from the past 14 days, with the full chat history remaining hidden.
- All participants receive a notification when history is shared, and the forwarded messages are clearly labeled with original timestamps and sender details.
- WhatsApp says the shared content stays end-to-end encrypted, and technical reporting notes a new key is generated with selected messages re-encrypted when someone joins.
- The feature is rolling out gradually on Android and iOS and can be turned off by group admins, aiming to reduce screenshots and manual forwards during onboarding.
