Migrate Signal from Chrome App to Standalone.

Google is dropping support for Chrome apps. If you don’t know what a Chrome app is, don’t worry – most people don’t use them.

I use the popular private messenger Signal on my phone, and there is a companion desktop program that runs as a Chrome app. Because Google is dropping support for Chrome apps, Whisper Systems has released a standalone desktop app.

There are three basic steps to migrate:

  • Export from the Chrome app
  • Import to the standalone desktop app
  • Remove the Chrome app.

Export From Chrome App

1. First, prepare by downloading and installing the standalone app from https://signal.org/download/. I’ve skipped those screenshots because they are so different between Windows and Mac. The desktop app installs like any other app for your computer. Full installation instructions are on the Signal website.

2. Launch the old Chrome App, click the three-dot menu and select Migrate to standalone.

4. You’ve already installed the Signal Desktop app in step 1, so click Install is complete.

5. Signal needs to export your chat history and security information. Click the Choose directory button to select where to save this information. I created a new folder on my desktop called Signal Export.

6. Signal will export your data. When finished, Signal will display a report. Close the Signal app.

10. Signal loads your data and then prompts you to restart.

(I missed this screen-shot, sorry.)

Click Restart Signal and verify it loads properly.

 

Uninstall Signal Chrome App

11. Click the three-dot menu, hover over More Tools and click on Extensions.

You are done.

Signal Desktop is now a full application, no longer using the Chrome App system. Otherwise, it looks and acts the same.
