Hello Nigel. Under your company settings, you can enable this functionality called multi-factor authentication. Once this is enabled users will have to input their random code generated to get access to the platform. This is inside the platform and we also have google authentication, so you can log into Pipefy using your Google Account. Please, take a look at this article that we wrote on our Help Page: https://help.pipefy.com/en/articles/2527885-multi-factor-authentication
