Given the ease with which Okta was recently penetrated, any company that asked me "should we use a SaaS offering for any sort of access control" would get a firm no. That said, I'm sure you'll make absolutely rude amounts of money with this. So good on you.
This is such a silly argument. It took Okta 11 years of being in business to get "hacked" once. What makes you think you'll be better at security than a vendor whose livelihood depends on it? Do you build your own door locks also?
