Umbera on your phone and your computer

Start on your phone: that’s where your account and its keys live. Then add your computer — Windows, macOS or Linux — with a QR code. Everything is free to install, and your chats show up on both.

Computer version 1.0 · Windows 10 and 11 (64-bit) · macOS 12 and newer (Apple Silicon and Intel) · Linux: Ubuntu 22.04, Debian 12, Fedora 36 and newer

Computer

Your computer links to your phone. Your account keys stay on the phone and are never copied to the computer.

Choose how you like to install apps. Every way gives the same Umbera; our repository and the Snap Store keep it up to date for you.

Link your computer in a minute

1. Open Umbera on the computer.

It shows a QR code that lives for one minute and renews itself.

2. On the phone: Settings → Linked devices → Add device.

Scan the code.

3. Compare the 6-digit code.

The same code appears on both screens. If it matches, tap “Link”. Contacts, chats and photos move over, encrypted all the way.

Why this is safe

Your account stays on the phone.

The computer gets its own keys, certified by your phone. It can’t change your password or delete your account.

Lost the computer?

Unlink it from the phone. When it comes back online, it erases its chats and keys by itself.

Up to 4 computers.

Every device in your account sees an alert when a new one is linked, with a “That wasn’t me” button.

Same encryption everywhere.

Messages, files, groups and calls from the computer use the same end-to-end and post-quantum encryption as the phone.
