transmitted data so that it cannot be read by unauthorized parties.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, when you log in to a website or email account, TLS ensures that your username, password, and other sensitive information remain private during transmission.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Data_Integrity\"><\/span>Data
