How can you secure the Sitecore admin login page?

The optimal approach to securing the Sitecore admin login page is through a combination of changing its URL, implementing IP restrictions, and using two-factor authentication. This method addresses multiple layers of security, making unauthorized access significantly more difficult.

Changing the URL for the admin page helps to obscure it from potential attackers who might be scanning for widely known default paths, reducing the risk of automated attacks. Implementing IP restrictions allows organizations to permit access only from specific, trusted IP addresses, further limiting exposure to threats. Two-factor authentication enhances security by requiring an additional verification step beyond the standard username and password, ensuring that even if login credentials are compromised, an additional layer of security is in place.

In contrast, requiring a Sitecore license does not inherently enhance the security of the login page itself, as it relates more to licensing compliance than protection against unauthorized access. Configuring password strength is beneficial for preventing weak passwords but does not address other vulnerabilities like URL exposure or unauthorized network access. Disabling the admin login page entirely would render the admin functionalities inaccessible, which is impractical for operational purposes. Therefore, the multifaceted approach outlined in the chosen option effectively secures the admin login while still allowing necessary access for administrators.
