True or False - My Domain registration is required before you can use Lightning components?

My Domain registration is indeed a prerequisite for using Lightning components in Salesforce. My Domain enables organizations to customize their Salesforce instance's domain name, offering a unique branding and security feature. Specifically, it is essential for applying user experiences in Lightning Experience and for utilizing several Lightning features effectively.

When My Domain is implemented, it allows for more tailored branding and enhances features like Lightning components and applications within a specific domain context. Additionally, various functionalities, such as Lightning App Builder and the availability of Lightning components in Communities, necessitate My Domain registration to ensure that they operate seamlessly and securely within the specified domain.

Without this registration, leveraging Lightning components for custom applications or experiences may not function properly, limiting the full potential of Salesforce's capabilities in building and deploying modern interfaces. This requirement aligns with Salesforce’s emphasis on security and customization, making My Domain registration a vital step for organizations aiming to effectively use Lightning components.
