WhatsApp is reportedly working on an update that will allow iPhone users to manage up to three accounts within a single app. The feature would expand on the multi-account support introduced for iOS, which currently allows users to add two accounts to the same device.
According to WABetaInfo, the option to add a third account was spotted in WhatsApp beta for iOS version 26.37.10.15, distributed through TestFlight. However, the feature is still under development and is not yet available to beta testers.

An Update To The Existing Multi-Account Feature
WhatsApp currently supports multi-account management on iOS and Android, allowing users to keep two accounts on the same device. The feature also supports independent account settings and chat data, making it possible to switch between accounts without signing out.
If released, the update would allow users with three phone numbers to manage all their WhatsApp accounts from the same iPhone. This could be useful for people who maintain separate personal, work and business accounts, without requiring a second device or repeatedly logging in and out.

Each Account Remains Separate
WABetaInfo says users who already have two accounts will reportedly see an “Add account” option to create another profile. The option may be accessible through the app’s settings or the existing “Switch accounts” menu.
As with the current multi-account feature, each account will retain its own chat history, notifications, backups, media and settings. Notifications will also indicate which account received a message, while App Lock can be configured separately for each account.
WhatsApp has yet to announce when support for three accounts will reach beta testers or become available to the general public. There’s also no indication whether it will be introduced on Android, though we wouldn’t discount that possibility.
