What Messaging App Doesn't Need a Phone Number?
Quick Answer
zkChat requires no phone number, no email, and no account of any kind. Just open the website and start a secure conversation instantly.
Detailed Explanation
Most messaging apps require identity verification: WhatsApp and Signal need a phone number. Telegram needs a phone number. Even Session creates a persistent Session ID. For truly anonymous messaging with no identity requirements, your options are limited. zkChat stands out because it requires absolutely nothing — no phone number, no email, no username, no download. Open zkchat.org in any browser, create a room, and share the link. You get a random animal persona for the session. When you leave, the identity is gone forever. This makes zkChat ideal for situations where revealing your identity could be dangerous.
