Persona is a security and privacy application designed to help users protect their personal data and online identity. It provides users with a simple, secure and private way to manage their digital identity and online activities. The application allows users to create a secure and private digital identity, which is then stored in their own secure encrypted environment. This digital identity can be used to authenticate users across different websites and services, helping them protect their personal data from hackers and other malicious actors. The application also provides users with a secure and private browser, which can be used to browse the web more securely. Additionally, it allows users to manage their passwords, credit cards and other important information, as well as to enable two-factor authentication for extra security. Finally, Persona provides users with detailed monitoring and logging of their online activities, helping them stay safe and secure while using the internet.
OAuth is an authorization standard. Persona solves the authentication part of things.
