Enhancing Security with “Less Secure Apps”

Google has always prioritized the security of its users. To ensure that Gmail accounts remain secure, Google introduced an additional layer of protection called “Less Secure Apps.” This feature blocks third-party servers that don’t meet Google’s security standards from accessing Gmail accounts.

However, enabling “Less Secure Apps” comes with certain risks. It’s generally not recommended unless no other option is available. If you have Google’s “Two Step Verification” enabled, you won’t be able to enable “Less Secure Apps.”


Understanding Gmail’s SMTP settings is crucial for anyone using this platform, especially businesses. With the added layer of “Less Secure Apps,” Google ensures that user data remains protected, even if it means sacrificing some convenience.
