Who We Are
The Account Security team is a full-stack team with expertise in backend, mobile, and web. Our goal is to protect users' Twitter accounts and identities by applying security standard methodologies. We believe in these principles:
- The best way to address account compromise is to detect and prevent it before it happens.
- Users should have the tools they need to protect themselves and their accounts.
- When we detect a compromise, we should move quickly to restore the account to a healthy state.
On the backend, we continue to maintain and improve Twitter's Login and OAuth systems that powers tens of millions of auth requests every single day. On the product side, we develop security features such as:
- Two-Factor Authentication
- Password Management and Reset Flow
- Login and Device Management
- Compromised Account Detection
- Frictionless Login
