WhatsApp works to close a linked devices loophole for locked chats.

Although you can currently “Chat Lock” sensitive WhatsApp conversations to put them in a password- or biometrics-protected folder, the same protection doesn’t carry across to other devices you’ve got linked to your account.

But code spotted in the WhatsApp’s Android app suggests that could soon change. “We also locked this chat on your linked device,” reads a screenshot of the in-development feature posted by WABetaInfo.
