Impact of personality traits (BFI-2-XS) on using Google or Facebook single sign-on for other web portals

Web portals used to require a separate login name and password for each portal. A relatively new development in this area is allowing to use a single sign-on login through another platform, such as Google or Facebook. The aim of this paper is to see whether personality traits influence use of such logins. It is possible that people more open to experience may use it more often in order to be able to access new platforms regardless other concerns they may have about it. It can be that more neurotic people will use it less often due to anxiety what could be consequences of such logins. More conscious people may also have some concerns, and therefore use it less. While more agreeable people, i.e. also more trustful, may use it more. The analysis is based on data from the Czech Republic, respondents were university students.
