Though App-specific passwords are not recommended by Google, it’s useful in some cases. For example, In a scenario when we want to utilize Google Mail as an SMTP provider, it’s more efficient to use an app-specific password than account credentials.
The process is very simple; however, you must have a two-factor password turned on.
Step – 1: Go to the Google Account settings page.
Step – 2: Navigate to the “Security” Tab, and locate the “Signing in to Google” section.
Step – 3: Click on the “App Password” link. This will navigate to the “App Passwords” page, but before we might need to authenticate.
Step – 4: Now, Select App and device, then click on the “Generate” button which will generate the application password. This password will be displayed only once, hence we need to copy-paste it before we close the window.
This app password can be utilized as per our requirements. For example, for SMTP settings we can use it as follows.
"smtpserver": "smtp.gmail.com",
"smtpport": "587",
"smtpusername": "--gmail email address—",
"smtppassword": "-- app specific password –",
