### We Make Mistakes

We, as humans, make **mistakes**, all the time. Software almost *always* has **bugs** hidden in different places. 🐛

And we as developers keep improving the code as we find those bugs and as we implement new features (possibly adding new bugs too 😅).

### Small Errors Automatically Handled

// IngressSpec describes the Ingress the user wishes to exist.
message IngressSpec {
  // ingressClassName is the name of the IngressClass cluster resource. The
  // associated IngressClass defines which controller will implement the
  // resource. This replaces the deprecated `kubernetes.io/ingress.class`
  // annotation. For backwards compatibility, when that annotation is set, it
  // must be given precedence over this field. The controller may emit a

You will get an "Inactive user" error, like:

```JSON
{
  "detail": "Inactive user"
}
```

## Recap

You now have the tools to implement a complete security system based on `username` and `password` for your API.

Using these tools, you can make the security system compatible with any database and with any user or data model.
