The use of messaging platforms, such as WhatsApp, has become deeply ingrained in peoples’ lives, and many digital services have started to be delivered using these communication channels. In this work, we propose a new OAuth grant type to be used when the interaction between the resource owner and the client takes place through a messaging platform. This new grant type firstly allows the authorization server to be sure that no Man-in-the-Middle risk exists between the resource owner and the client before issuing an access token. Secondly, it allows the authorization server to interact with the resource owner through the same user-agent already being used to interact with the client, i.e., the messaging platform, which is expected to improve the overall user experience of the authorization process. To verify this assumption, we conducted a usability study in which subjects were required to perform the full authorization process using both the standard authorization code grant type (through a web-browser) and the new grant type defined in this work. They have also been required to fill in a small questionnaire including some demographic information and their impressions about both authorization flows. The results suggest that the proposed grant type eases the authorization process in most cases. info:eu-repo/grantAgreement/ES/DGA-FEDER/T31-20R info:eu-repo/grantAgreement/ES/DGA-MECD/FPU15-04841 info:eu-repo/grantAgreement/ES/MINECO-FEDER/TIN2016-76770-R info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 3.847 2021 CHEMISTRY, ANALYTICAL 29 / 87 = 0.333 2021 Q2 T2 INSTRUMENTS & INSTRUMENTATION 19 / 64 = 0.297 2021 Q2 T1 ENGINEERING, ELECTRICAL & ELECTRONIC 95 / 277 = 0.343 2021 Q2 T2 0.803 2021 Analytical Chemistry 2021 Q1 Biochemistry 2021 Q1 Instrumentation 2021 Q1 Information Systems 2021 Q1 Electrical and Electronic Engineering 2021 Q1 6.4 2021 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion García Moros, José Universidad de Zaragoza (orcid)0000-0001-9485-7678 Alesanco Iglesias, Álvaro Universidad de Zaragoza (orcid)0000-0002-5254-1402 5008 560 Universidad de Zaragoza Dpto.
