Security Assertion Markup Language (SAML) is a way of using special codes to help keep your data safe. It works by giving a website or app an extra way to make sure that you are who you say you are. When you sign in to an account, SAML makes sure that all your information is securely passed from one website or app to the next, so nobody else can access it. To do this, it creates a long code, like a password, that is used to make sure only the right people are getting access.
