Keycloak OTP Validation API

openidc_otp_validation.sh

BASE_URL=https://localhost:8081/auth
CLIENT_ID=curl-test
CLIENT_SECRET=
USERNAME=
PASSWORD=
REALM=validation-test
OTP_CODE=027253

# OpenID Access Token via "Resource Owner Password Credentials Grant"
# https://tools.ietf.org/html/rfc6749#section-4.3
ACCESS_TOKEN=$(curl -s scope=openid \
  	--data-urlencode client_id=$CLIENT_ID \
   --data-urlencode client_secret=$CLIENT_SECRET \
  	-d grant_type=password \
  	--data-urlencode username=$USERNAME\
  	--data-urlencode password=$PASSWORD \
   $BASE_URL/realms/$REALM/protocol/openid-connect/token \
	  | python -c 'import sys, json; print json.load(sys.stdin)["access_token"]')

## Validate otp token with custom credential validation endpoint
curl -v \
  -H "Authorization: Bearer $ACCESS_TOKEN" \
  -H "Content-Type: application/json" \
  -d "[{"\""type"\"":"\""totp"\"","\""value"\"":"\""$OTP_CODE"\""}]" \

@jasw @rafakwolf @dileepkumar457 I was initially running into the same issue, as I picked up some ideas from a mailing list message, which described an extended credential-validation API from a patch which a user had implemented on his own. So please ignore the example above, it was only used as an example when I wrote to the mailing list, it will only work with his own credentials-validation module.

Keycloak is not able to validate the TOTP token apart from username and password; so i had to wait on my RP (freeradius) until I get username, password & token to send it to Keycloak using the following request:

#!/usr/bin/env bash

# Metadata Discovery
#curl https://auth.local/auth/realms/ono/.well-known/openid-configuration | python -m json.tool

set -x

BASE_URL=https://auth.local/auth
CLIENT_ID=radius
CLIENT_SECRET=aaaaaaa-bbbb-cccc-dddd-eeeeeee
USERNAME=alice
PASSWORD=xxxxxxxx
REALM=ono
OTP_CODE=1234

curl --trace -vvv -s scope=openid \
    --data-urlencode client_id=$CLIENT_ID \
    --data-urlencode client_secret=$CLIENT_SECRET \
    --data-urlencode username=$USERNAME\
    --data-urlencode password=$PASSWORD \
    --data-urlencode totp=$OTP_CODE \
    --data grant_type=password \
          $BASE_URL/realms/$REALM/protocol/openid-connect/token

@dileepkumar457 , @rafakwolf I'll upload my solution soon. I implement a module to check the totp on keycloak via an api. I'll post the link here soon.

Hi there
@fatihATtargens did you come to a solution please?

i'm looking for a username+otp validator rest endpoint without specifying the password (should be used to protect external password reset page)

can anyone help here?
