That's also an argument for just using Kerberos over the Internet. And I'm not sure that's a good idea.

I'm almost certain it's a bad idea if that means rolling your own Kerberos implementations in php, javascript and golang in order for your various back-end to speak to your various front-ends.

But sure, leverage secret-key crypto and tickets in your own implementation in a way that's more secure than Kerberos.

Or, use a solution that's simple enough any weakness is fairly obvious.
