But here's the key point.

The security and dependency injection stuff is written once.

And you can make it as complex as you want. And still, have it written only once, in a single place. With all the flexibility.

But you can have thousands of endpoints (*path operations*) using the same security system.

## Recap { #recap }

With what you have seen up to now, you can set up a secure **FastAPI** application using standards like OAuth2 and JWT.

In almost any framework handling the security becomes a rather complex subject quite quickly.

    String SELF_COMBINATION_REMOVE = XmlService.SELF_COMBINATION_REMOVE;

    /**
     * In case of complex XML structures, combining can be done based on id.
     */
    @Deprecated(since = "4.0.0", forRemoval = true)
    String ID_COMBINATION_MODE_ATTRIBUTE = XmlService.ID_COMBINATION_MODE_ATTRIBUTE;

    /**
     * In case of complex XML structures, combining can be done based on keys.
     * This is a comma separated list of attribute names.

The most common is the implicit flow.

The most secure is the code flow, but it's more complex to implement as it requires more steps. As it is more complex, many providers end up suggesting the implicit flow.

/// note

It's common that each authentication provider names their flows in a different way, to make it part of their brand.

        ASN1EncodableVector authDataVector = new ASN1EncodableVector();
        ASN1EncodableVector authElementVector = new ASN1EncodableVector();
        // Use an auth type that doesn't require complex parsing (e.g., 999 - unknown type)
        authElementVector.add(new DERTaggedObject(0, new ASN1Integer(999))); // ad-type
        authElementVector.add(new DERTaggedObject(1, new DEROctetString(new byte[] { 1, 2, 3, 4 })));
