Answer 1

If anyone comes looking. The dev mode credentials for the embedded db can be found in the DatabasePropertyMappers class.
For now it seems to be:
username: sa
password: password

private static Optional<String> resolveUsername(Optional<String> value, ConfigSourceInterceptorContext context) {
if (isDevModeDatabase(context)) {
return of("sa");
}
return Database.getDatabaseKind(value.get()).isEmpty() ? value : null;

private static Optional<String> resolvePassword(Optional<String> value, ConfigSourceInterceptorContext context) {

For Quarkus Distribution
You can check the default configuration in keycloak.conf file. Search for keycloak.conf file in your keycloak directory. The database-related properties will look something like below.
db=dev-mem
db-username = sa
db-password = keycloak
For Wildfly Distribution
You can check for the h2 database username and password in standalone.xml or domain.xml.
Under datasources subsystem look for java:jboss/datasources/KeycloakDS named data source. e.g.
<datasources>
​<drivers>
​<driver name="h2" module="com.h2database.h2">
​<xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class>
​</driver>
​</drivers>
...
<datasource jndi-name="java:jboss/datasources/KeycloakDS" pool-name="KeycloakDS" enabled="true" use-java-context="true">
<driver>h2</driver>
<connection-url>jdbc:h2:${jboss.server.data.dir}/keycloak;AUTO_SERVER=TRUE</connection-url>
<security>
<user-name>sa</user-name>
<password>?</password>
</security>
</datasource>
...
</datasources> ```
