What is a Gmail App Password?

A Gmail App Password is a 16-character passcode that allows third-party apps or devices to securely access your Google account. It is mainly used when setting up SMTP (Simple Mail Transfer Protocol) for sending emails from applications.

Important: You must enable 2-Step Verification on your Google account before generating an App Password.
