A depth layer beneath user-authentication-protocols, focused specifically on the implementation mistakes that recur across real deployments of JSON Web Tokens (JWT), OAuth 2.0 and Security Assertion Markup Language (SAML). You will learn why authentication infrastructure is a uniquely high-value target, the concrete JWT verification failures that recur in practice including algorithm confusion, the genuine design challenge of revoking a stateless token and the mitigation patterns that manage it, OAuth redirect Uniform Resource Identifier validation and the state parameter's role in preventing cross-site request forgery within the flow itself, SAML signature wrapping described conceptually, and a practical review checklist you can apply to an existing integration of any of the three protocols. Every example uses a clearly labelled hypothetical application; no working exploit chain is provided.
Nothing. Every course, exam, and certificate on the catalog is free — including retakes. All you need is a free Safeguard account.
None. The flagship course, Safeguard Certified Practitioner, is a beginner-level course — basic familiarity with how software is built helps, but every exam question is answerable from the lessons themselves.
You can retake it after a 24-hour cooldown, as many times as you need. Retakes are free, and each attempt draws a fresh random set of questions.
The Safeguard Certified Practitioner credential is valid for 24 months from issue. The expiry date is printed on the certificate and shown live on its public verification page. Renewing means passing the current exam again.
