To lock your messages, go to “Settings”, “Privacy and Security” and tap on “Passcode Lock”. You will be asked to set a four-digit passcode and confirm it. Once you do that, you will find additional options to “unlock the app with fingerprint” and “auto-lock” it after a specific duration. To do this, long-press on a picture you have sent. Choose the ‘Edit’ button on the top, just like you’d edit a text message once you have sent it. Now, you will get an in-built photo editor where you can add filters, draw or crop images. Alternatively, you can even replace the picture and send another one in its place. As mentioned above, the use of usernames instead of phone numbers means your account isn’t tied to just one phone.

Set Reminders To use live locations and proximity alerts, go to the contact’s chat window and tap on the ‘Attach’ icon shaped like a paperclip. Choose the location button here, and choose ‘Share my Live Location’. You will be able to send live locations for either 15 minutes, 1 hour or 8 hours.
