I'll start this by saying that I've never used Salesforce.
I've been given the task to investigate if it's feasible for the company I work for to create a Salesforce app that provides an authentication feature through our services, similar to oAuth. I'm going through the documentation, but it's hard for me to understand if there's a need for something like this.
If yes, can anybody point me in the right direction on how to approach the development? Thanks.
