OAuth 2.0 Security Reinforced

Dr. Torsten Lodderstedt
Wednesday March 11, 16:00 - 17:30
Short description

OAuth 2.0 has become the standard for API authorization. Practical experience and security research have shown a need for updated security guidelines that will be presented in this session.


The OAuth working group recently decided to discourage the use of the implicit grant. However, that's just the most prominent recommendation that will be published in the upcoming OAuth 2.0 Security Best Current Best Practice ( The password grant is discouraged as well, the code flow shall be used with PKCE only, and tokens should be sender-constrained to mention a few. This session will present the new security guidelines in detail, along with the underlying rationales.
