Viber adds end-to-end encryption and hidden chats as messaging app privacy wave grows
Following WhatsApp's move to add end-to-end encryption to its platform, another big messaging company is joining the wave of apps turning on expanded privacy features. Viber — a messaging app …
Context & Ripple Effects
Viber's move lands mid-wave rather than at its start: WhatsApp switched on end-to-end encryption first, and by that autumn Facebook Messenger had finished rolling out Secret Conversations to its 900M+ users as an opt-in layer. What sets Viber apart is bundling encryption with hidden chats — a thread it extended months later with [[a:917203|secret chats that self-destruct after a preset time, cannot be forwarded, and block screenshots on Android]].
First-order effects
- Viber's existing user base gains encrypted messaging plus hidden chats inside an app they already use, closing the privacy gap that WhatsApp's earlier switch opened between the two services.
Second-order effects
- Encryption stops being a selling point and becomes table stakes: Telegram leaned on end-to-end claims when launching voice calls, signaling that privacy now fronts even non-messaging feature rollouts among Viber's direct rivals.
Third-order effects
- If defaults converge on encryption across the major messengers, differentiation migrates to granular controls — expiring, non-forwardable, screenshot-proof chats — while regulators' lawful-access demands collide with a baseline no longer framable as a niche feature.
The trend: End-to-end encryption is hardening from differentiator into default across consumer messaging apps, pushing competition toward ephemeral and anti-forwarding controls.
