OpenID Support


OpenID Connect is an authentication protocol, built on top of Oath 2.0, that can be used to securely sign users in to web applications. e-Share has implemented OpenID Connect and developed integrations with Microsoft, Google and Yahoo to allow recipients of Trusted Shares to be authenticated by these email service providers via their associated identity platforms.
