Frequently Asked Questions
What is the difference between Authentication and Authorization?
Authentication verifies who you are (AuthN - e.g., OpenID Connect); Authorization verifies what you are permitted to do (AuthZ - e.g., OAuth 2.0 scopes, RBAC).
Why is OAuth2 Authorization Code with PKCE recommended?
Proof Key for Code Exchange (PKCE) prevents authorization code interception attacks, making it mandatory for single-page applications and mobile apps.
Which certifications help IAM careers?
Okta Certified Professional/Administrator, Microsoft Certified: Identity and Access Administrator Associate (SC-300), and CIAM.
