Adding A Google Account
Local Viking automatically authenticates with your Google Accounts upon clicking the 'Add Account' button on your dashboard (https://www.localviking.com/google_accounts):
Once you click this button your browser will be redirected to Google and you can choose which account you want to authenticate with. Once you've granted permissions to your account, you will then be redirected to your Local Viking dashboard where you can add a description for the Account while your data syncs.
There is currently no limit to the amount of Google accounts you can attach to your Local Viking account.
