 [Multi-factor authentication](https://brave.com/glossary/multi-factor-authentication/)
 Multi-factor authentication (MFA) is a login process that requires multiple forms of proof of identity, often including a password, biometric data, or a security token. When logging in, a person provides an identity-such as a username or email-and then authenticates this identity by providing additional information such as a password. Each authenticating item is called a factor. MFA requires more than one factor to authenticate the individual's stated identity. A common MFA setup is a user ID followed by a password and then a 6-8 digit temporary code.
 ## O
+[OAuth](https://brave.com/glossary/oauth/)
+OAuth, short for "open authorization," is an open protocol commonly used to grant websites or apps access to user info stored on other websites, all without sharing passwords. With OAuth, a person can selectively and securely allow two websites to interact directly, with the goal of making a particular task easier. OAuth grants permission or authorization to access data, which is different from authenticating an identity (such as when a user logs into a service).
 [Open source](https://brave.com/glossary/open-source/)
 Open-source software is software whose source code-the instructions that define what the software does-is published and freely available. The opposite of open source is closed source. Source code is human-readable, and software developers create software by writing it. To run software on a device, though, the source code has to be transformed into a form that's mostly unreadable to humans. That unreadable form is what you get when you download an app. Open-source software is often developed in a collaborative manner, and considered a public good, free for anybody to use. The Brave Browser, Linux operating system, and OpenOffice are examples of open-source software.
 ## P
 [Partitioning](https://brave.com/glossary/partitioning/)
 Partitioning is the process of separating an individual's browsing data from one website to another, as a countermeasure against the trackers embedded in third-party ads. These trackers will otherwise attempt to identify individuals and track their activity across websites.
 [Passkey](https://brave.com/glossary/passkey/)
+A passkey is a unique secret code that gives you secure access to a system or online service. Each passkey is specific to the user and the service; passkeys can't be reused for multiple logins. Once a passkey is set up, the user can optionally add a second factor of authentication-like a fingerprint, face scan, or PIN-to enhance the security of the login experience.

 [Password manager](https://brave.com/glossary/password-manager/)
 A password manager is software that stores the usernames and passwords to your online accounts. It can automatically fill in usernames and passwords on login pages, generate new random passwords, and sync your passwords across multiple devices. Using a password manager can save you a lot of hassle and-when used properly-dramatically improve your privacy, safety, and security online.
