We use Google services to sign on to a range of Web Applications as contractors for a company. But they have locked this address and state that this address enables file sharing - which I'm pretty sure it doesn't, it just enables you to login to another service that allows file sharing such as Google drive or Gmail. They previously had drive and Gmail locked, so I don't have a problem with that. But we chose the remaining application we use for timesheets etc based on them providing Google sign in.
Probably a ridiculous question, but is there any other to authenticate to Google?
