2FA vs ABAC

The key difference: 2FA refers to two-factor authentication, while ABAC refers to attribute-based access control — they describe different things even when they show up in the same sentence.
2FA — Two-Factor Authentication
Login that requires something you know (password) plus something you have (code, key, device). 2FA blocks the vast majority of credential-stuffing and phishing attacks at near-zero cost.
ABAC — Attribute-Based Access Control
Access model that grants permissions based on attributes of the user, resource, and context (location, time, device). ABAC scales where RBAC breaks — when "what you can do" depends on more than just your title.
