> Can someone explain why people still choose Okta? I personally feel way more comfortable using GSuite as an IDP. Okta suffered a pretty terrible breach and, candidly, I hadn't heard great things about their security practices before that.
Have you actually used Google Workspace for anything serious? It's one of the least capable IDPs out there, with Okta being one of the most capable. Comparing the two is like comparing a bicycle to a motor bike because they both have two wheels. Frankly, I'm surprised to read anyone on a technical forum recommend Google Workspace as an IDP.
