What does the "authentic" mean? Could you give me some examples?

Native speaker’s answer

To be authentic means to be genuine and real, in a way that does not seem fake or unreal. For example, you can tell when people are being nice in a fake way. The speaker recommends that you behave in a real and down-to-earth way, to leave a better impression. Ex: I love her because she shows her authentic self to everyone. Ex: She's so authentic and true to herself. She doesn't try to impress anyone.
