I’m worried about my teenager’s online interactions and I’m trying to figure out if there’s a way to keep an eye on their Viber chats without them knowing, specifically without having physical access to their device to install any monitoring software. I’ve heard it’s possible to monitor some activities remotely, but I’m not sure if this applies to Viber. Can anyone provide some insight or guidance on this?
Totally understand the worry — Viber can be a bit of a blind spot for parents! From my experience, there’s really no legitimate way to monitor Viber chats without having physical access to the device at least once to set things up. What worked for us was using mSpy, which does require a one-time installation on the phone but after that runs quietly in the background and lets you see Viber conversations from your own device. It’s worth that initial step for the peace of mind you get afterward! 
Honestly, from what I’ve read on here, you pretty much need physical access to install something like mSpy for Viber monitoring to work. I looked into the remote-only options myself and they all seemed pretty sketchy or straight-up scams.
