OAuth Security Workshop

The aim of the OAuth Security Workshop (OSW) is to improve the security of OAuth and related Internet protocols by a direct exchange of views between academic researchers, IETF OAuth Working Group members and industry.
While the standardization process of OAuth ensures extensive reviews (both security and non-security related), further analysis by security experts from academia and industry is essential to ensure high quality specifications. Contributions to this workshop can help to improve the security of the Web and the Internet.
The OAuth Security Workshop runs over three days - enough time for in-depth discussions and break-away sessions. Although the main focus is security there is room for other related topics.
OSW 2020 will be the 5th workshop this far. The previous events were held at:

Submit your proposals for talks and sessions

We seek proposals for sessions (talks, interactive discussions, ...) and tutorials related to OAuth, OpenID Connect, and other technologies using OAuth under the hood. Contributions regarding technologies that are used in OAuth/OIDC or impact the security of OAuth, such as JOSE or web technology, are also welcome.

Areas of interest where OAuth can be used as enabler of innovative scenarios include:
  • Financial, e-government and health applications
  • Mobile and Strong authentication.
  • Federated Identity.
  • Privacy-enhancing technologies.
  • IoT

The Venue

This years conference will be held in the centre of Trondheim at the Scandic Hotel Nidelven, which is situated by the banks of Nidelven river.
You will eat lunch overlooking the river, and if you are considering to stay at the conference hotel you'd might like to know that the hotel has been awarded with the prize for "best hotel breakfast in Norway" 12 years consecutively.

Trondheim was founded in 997 AD, and served as the capitol during the viking era. The city is, among other things, proud of its beautiful cathedral Nidarosdomen and the small island of Munkholmen which has served as both monestary, prison and fortress.

There are around 190000 inhabitants, and the city's university (NTNU) and colleges hosts around 33000 students in Trondheim.

Although Trondheim is quite close to Hell, it has something to offer for most people. You can find more information at Visit Trondheim

If you would like to stay somewhere else there are several alternatives for accommodation. We recommend that you stay in or close to the city centre as public transportation services are reduced during the summer.



We recommend taking the bus when traveling to/from the airport. There are two different bus companies that run the airport service, either is ok.
Avinor has a description of the service. The buses are waiting right outside the arrivals in the airport.
