# Network Activity

As with any security product, you may wish to know what network activity 1Password and its components engage in. This article reviews 1Password’s network activity.

There are three types of network activity that 1Password 3 for Mac can engage in: Checking for and installing updates, fetching site icons and previews, and WiFi sync with 1Password on iOS. 1Password for Windows checks for updates and fetches previews and icons.

1Password on iOS, Android and Windows 7 Phone systems will communicate directly with Dropbox. 1Password on iOS additionally can use WiFi sync and listen for connections for its Backup & Restore feature.

## Updates

1Password can periodically check for updates depending on your configuration. The connections may be initiated either by 1Password itself or a component called 1PasswordUpdater from within the 1Password application bundle. Connections will be made to servers within our domains: agilebits.com, agilewebsolutions.com, agile.ws, and additionally aws.cachefly.net.

You may configure 1Password’s updating behavior in the Updates pane of Preferences.

## Previews and icons

When you create a new Login 1Password will contact the web site to generate a page preview which is displayed in the detail view of the Login. It will also try to fetch apple-touch-icon.png and favicon.ico from the web server. This are used for displays in shelf and list views of your data. 1Password does not send any information to the sites it fetches these from other that the actual URL you have stored for the site.

If 1Password cannot do the fetching immediately when the Login is created, then it will periodically try to get these at a later time. This can happen, for example, when a Login is created on 1Password iOS, which doesn’t fetch icons, and then synchronized with 1Password for Mac or Windows, which do fetch icons and previews. In these cases on the Mac the connection will be initiated by 1PasswordThumbs.app within the 1Password application bundle.

You may control automatic preview fetching in the Logins preferences pane by checking or unchecking “Automatically download icons and previews for new Logins” in the Logins preference pane.

## Dropbox Synchronization

1Password for Mac and Windows do not communicate directly with Dropbox. They will just read and write files within your Dropbox folder on your local machine. The communication with Dropbox servers will all be done by the Dropbox application running on your Mac or PC.

1Password on iOS, Android, and Windows 7 Phone systems will communicate with Dropbox using the information that you have provided it. If you have set up automatic Dropbox syncing then 1Password will work to ensure that the data on your device and the data stored on Dropbox are in sync.

## WiFi Synchronization

1Password for Mac can synchronize data with 1Password on iOS using WiFi Sync. This is not as flexible or robust as the more recently introduced Dropbox syncing, but some users may still be using this. 1Password on the Mac and on iOS find each other using the Bonjour service. Once they do find each other, 1Password on the Mac will initiate a connection to the device using the information provided through Bonjour. This is limited to the local network.
