Two factor authentication, or 2FA, is a security process where a user provides two distinct forms of identification before gaining access to an account, system, or application.
In identity and access management (IAM) architectures, 2FA acts as a security gate within the authentication workflow, enforcing multi-layered defence.
Authentication Factors look to combine two distinct pieces of information.
Authentication Factors look to combine two distinct pieces of information.
- A knowledge Factor, which could be passwords, PINs, or secret answers.
- A possession Factor, such as One Time Passcode (OTP), secondary apps e.g., Google Authenticator, Authy, etc.Â
- An Inherence Factor is something you are. Your biometric data for Face ID, a fingerprint scanner, or even iris scans for secret agents or super villains!Â
For testing, you can mock 2FA endpoints in non-production environments to avoid dependencies on third parties. In automation, secret keys can work in test environments to generate valid OTP tokens within end-to-end UI tests. You can also implement conditional test configurations or feature flags (e.g., test-only OTPs or environment-level 2FA bypass) specifically for CI/CD pipeline runs.
