Gmail’s API lockdown will kill some third-party app access, starting July 15

Google is locking down API access to Gmail data (and later, Drive data) soon, and some of your favorite third-party apps might find themselves locked out of your Google account data. The new policy closes off OAuth access to Gmail data, and while we by no means have a comprehensive list of what isn’t affected yet, so far we’ve seen users of Microsoft’s SwiftKey and the open source app SMS Backup+ receive notification emails. “We wanted to let you know that the following apps may no longer be able to access some data in your Google Account, including your Gmail content,” the email reads.
