This means that you are signing into your Evernote account on the Evernote system – you are not giving the Third Party Application your Evernote credentials. Here’s how OAuth works: When the Third Party Application needs to access your Evernote account, it will direct you to Evernote's servers, where you will be prompted to log into your Evernote account with your Evernote username and password. The OAuth process allows you to authorize Evernote to give a specified Third Party Application a token which in turn allows the Third Party Application to access your account without needing your Evernote username and password. Most Third Party Applications use a process called “OAuth” to obtain permission to access your account. Evernote will not transfer your email address to a Third Party Application without your permission, and will never transfer your password to any Third Party Application. To start, it is important to note a Third Party Application needs your express permission in order to access your account. This document will help you understand how such Third Party Applications access your Evernote account.

There are many ways to access your Evernote account, including using applications published by Evernote as well as applications published by third party developers (“Third Party Applications”).
