Dropbox Sign provides two-factor authentication for our paid subscriptions using SMS but all users have the ability to set up two-factor using Google Authenticator.
Before you get started, if you don't already have the app, you will need to download Google's Authenticator from either iTunes or the Google Play store.
Once you have the app downloaded, follow the steps below.
- Hover over your email address in the top-right corner of any screen in your account and click Settings.
- Click the Profile tab in the settings menu.
- Scroll down to the 2-FACTOR AUTHENTICATION section and click Enable next to Google Authenticator.
- A pop-up window will appear with the barcode you'll need to scan. Open the Google Authenticator in your phone to scan the barcode.
- Once scanned, enter in the code which has been populated in your app and click Verify.
