== Configuring a default provider
== Configuring a single provider for an SPI
Depending on the SPI, multiple provider implementations can co-exist but only one of them is going to be used at runtime.
For these SPIs, a default provider is the primary implementation that is going to be active and used at runtime.
For these SPIs, a specific provider is the primary implementation that is going to be active and used at runtime.
To configure a provider as the default you should run the `build` command as follows:
To configure a provider as the single provider you should run the `build` command as follows:

.Marking the `mycustomprovider` provider as the single provider for the `email-template` SPI
<@kc.build parameters="--spi-email-template-provider=mycustomprovider"/>
In the example above, we are using the `provider` property to set the id of the provider we want to mark as the default.
== Configuring a default provider for an SPI
Depending on the SPI, multiple provider implementations can co-exist and one is used by default.
For these SPIs, a specific provider is the default implementation that is going to selected unless a specific provider
is requested.
The following logic is used to determine the default provider:
1. The explicitly configured default provider
2. The provider with the highest order (providers with order <= 0 are ignored)
3. The provider with the id set to `default`
To configure a provider as the default provider you should run the `build` command as follows:
.Marking the `mycustomhash` provider as the default provider for the `password-hashing` SPI
<@kc.build parameters="--spi-password-hashing-provider-default=mycustomprovider"/>
== Enabling and disabling a provider
