Moving from SimpleX Chat to AChat
A messenger with no user identifiers at all, not even random ones. Choose SimpleX if having no identifier of any kind matters most to you. Choose AChat if you want people to find you by username, and anonymous rooms you can share or embed.
Last checked 2026-11-07. The full comparison is on AChat and SimpleX Chat.
How to move across
- Sign in to AChat and pick a username. It asks for no phone number.
- Tell the people you talk to on SimpleX Chat your username, or send them your link or QR code (personal chats and contacts).
- Save your recovery key somewhere only you can reach (devices and recovery). It's what brings your history back if you lose every device.
- Keep SimpleX Chat open until the people you need have moved. AChat doesn't import chats from other apps.
How they differ
| Feature | AChat | SimpleX Chat |
|---|---|---|
| Sign up without a phone number | Yes | Yes (their page) |
| End-to-end encryption on personal chats | Yes | Yes (their page) |
| History comes back on a new device | Partly | Yes (their page) |
AChat has no voice or video calls. Your encrypted history comes back only with another linked device or your recovery key. Lose both, and nobody can restore it, including us.
