Powered by Outfunnel. OAuth2 allows your application to store and use authentication tokens instead of actual login credentials. Access Tokens needed for OAuth2 authentication are short lived so these need to be regenerated from time to time. Nodemailer is able to use both 3LO and 2LO to automatically regenerate the tokens but you can also handle all token specific yourself. Your application requests permissions from the client and gets a refresh token in return that can be used to generate new access tokens.
Normal SMTP transport ie. This allows you to set up a transport with just clientId and clientSecret values and provide accessToken and refreshToken with the message options. See example 5. Nodemailer also allows you to use service accounts to generate access tokens. In this case the required auth options are a bit different from 3LO auth. If you do not want Nodemailer to create new access tokens then you can provide a custom token generation callback that is called every time a new token is needed for an user.
Use an existing Access Token. If the token is not accepted then message is not sent as there is no way to generate a new token. This example requests a new accessToken value from a custom OAuth2 handler.
Nodemailer does not attempt to generate the token by itself.
This example uses an existing Access Token. If the token is not accepted or current time is past the expires value, then refreshToken is used to automatically generate a new accessToken. If the token is not accepted or current time is past the expires value, then a new accessToken value is generated using provided service account.
This example demonstrates how to authenticate every message separately. This is mostly useful if you provide an email application that sends mail for multiple users. Instead of creating a new transporter for every message, create it just once and provide dynamic details with the message options.

OAuth is a token-passing mechanism that allows a system to control which external applications have access to internal data without revealing or storing any user IDs or passwords.
In Magento, a third-party extension that uses OAuth for authentication is called an integration. An integration defines which resources the extension can access. The extension can be granted access to all resources or a customized subset of resources. As the process of registering the integration proceeds, Magento creates the tokens that the extension needs for authentication.
It first creates a request token. This token is short-lived and must be exchanged for access token. Access tokens are long-lived and will not expire unless the merchant revokes access to the extension. The following diagram shows the OAuth authentication process.
Each step is described further. Create an integration. The merchant creates an integration from Admin. Magento generates a consumer key and a consumer secret.
Activate the integration. The OAuth process begins when the merchant activates the integration. See Activate an integration for more information. Process activation information. The integrator must store the activation information received in step 2. These parameters will be used to ask for tokens. Magento calls the page defined in the Identity Link field in Admin.
Merchant logs in to the external application. If the login is successful, the application returns to the location specified in the call. The login page is dismissed. Ask for a request token. The Authorization header includes the consumer key and other information. See Get a request token for details about this token request. Send the request token. Magento returns a request token and request token secret.
Ask for an access token. The Authorization header includes the request token and other information. See Get an access token for details about this token request.Setting up video conferencing for remote work?
