App passwords (sometimes called “app-specific passwords”) are randomly generated passwords that provide a secure way for users to authenticate with third parties such as Nylas, without using their regular account password.
Because every provider has a different way of creating an app password, you must direct your user to their provider’s app password tool so they can create one. When that’s done, they can complete the authentication process with Nylas.
When you use the Detect Provider endpoint, Nylas includes a link to the detected provider’s app password tool, if one is available.
