All users are required to connect with LinkedIn to access their EverTrue account, as we use LinkedIn's standard authentication to validate each user of the platform. We partnered with LinkedIn as they take user privacy very seriously and rely on the industry standard protocol for authorization, OAuth 2.0 protocol. EverTrue uses LinkedIn authentication for basic information only (name, email, and connections) and never accesses your private information, like messages and invitations. Additionally, EverTrue does not share your data with LinkedIn, Facebook, or any other 3rd party.
