Please note: preferable way to authorize within Gmail is 2-step verification. In order to set up the verification follow the steps here.
The alternative (NOT recommended) way to use the Gmail account as an SMTP server is to allow connection to mail for third-party applications.
To do it, please follow the next steps:
Step 1. Sign in to your Google Admin console.
Step 2. From the Admin console Home page, go to Security tab.
Step 3. Turn on access for third-party applications as shown in the screenshots.
Step 4. Return to the custom SMTP server configurations and fill in the fields as described:
Name - a required field, name of the SMTP server.
From address - a required field, the default address which will be used for outbound mail.
Email prefix - a required field, this prefix will be prepended to all outgoing email subjects.
Service Provider - select Gmail server provider from the list
Username - username of your email account (example email@example.com).
Password - password to your email account.
Test Connection - allows you to check the connection to the SMTP server. In case of an unsuccessful connection, an error message appears.
Save - saves all data and creates Gmail server as configured.
Cancel - allows you to return to the “Custom SMTP server” page without saving data.
