Enabling Chromium to sync with Google Account

You'll need to set three environment variables:

On Windows: Launch cmd.exe and enter the following commands:

setx GOOGLE_API_KEY ""
setx GOOGLE_DEFAULT_CLIENT_ID 77185425430.apps.googleusercontent.com
setx GOOGLE_DEFAULT_CLIENT_SECRET OTJgUOQcT7lO7GsGZq2G4IlT

On Mac OS X / Linux: Plop these in your ~/.profile file:

export GOOGLE_API_KEY=""
export GOOGLE_DEFAULT_CLIENT_ID="77185425430.apps.googleusercontent.com"
export GOOGLE_DEFAULT_CLIENT_SECRET="OTJgUOQcT7lO7GsGZq2G4IlT"
Now launch Chromium:

On Windows: Launch Chromium normally.

On Mac OS X:

/Applications/Chromium.app/Contents/MacOS/Chromium
