[keycloak-user] Can't invoke Keycloaks OpenID Connect token endpoint with grant type set to password

[Виталий Ищенко]

You need to pass client secret, note this part in provided json:
"clientAuthenticatorType"
: "client-secret"

You can find client secret on UI or use kcadm.sh

./keycloak/bin/kcadm.sh get clients/f3c2109d-9eb0-4fb3-b6be-32a52a691d42/
*client-secret* -r demo-realm
