Best chat apps with no signup required (2026)
Most apps that claim "no signup" still want your phone number or your Apple ID. This list is stricter: zero account, zero phone, zero email, zero installs. Just open and chat.

What "no signup" really means
The phrase is abused. Some apps say "no signup" but require Apple/Google sign-in (which exposes your real name to the platform). Others require a phone number that they SMS-verify (the largest anonymity leak available). For this list we required:
- No email collected (even optional "for recovery" counts against).
- No phone number, SMS verification, or carrier billing.
- No real name disclosed to the platform.
- No app install required (browser version available).
