Re: [keycloak-dev] OTP API

Hello guys, I agree with you Bill that requiring a user to re-auth by redirecting to the auth-server is often the best thing to do. However in business applications one often sees the requirement to periodically reauthenticate the user without requiring the user to login again (e.g. without leaving the application). A common example for this is that users need to reenter a OTP credential before performing a certain critical operation... I gave this a quick spin... https://github.com/thomasdarimont/keycloak/commit/ e891ca604acf5fd494525092c7a88628d9fb20bd as you can see I took some inspiration from the userinfo endpoint. Works quite well so far, but bruteforce protection is still missing. A demo session via curl looks like this: $ KC_REALM=otp-validation-test KC_USERNAME=tester KC_PASSWORD=test KC_CLIENT=test-client KC_CLIENT_SECRET=c57dc179-09bb-4bb7-9128-91b29dd7fc35 KC_URL="http://localhost:8081/auth" ## Request Tokens for credentials KC_RESPONSE=$( \ curl -v \ -d "username=$KC_USERNAME" \ -d "password=$KC_PASSWORD" \ -d 'grant_type=password' \ -d "client_id=$KC_CLIENT" \ -d "client_secret=$KC_CLIENT_SECRET" \ "$KC_URL/realms/$KC_REALM/protocol/openid-connect/token" \ | jq . ) KC_ACCESS_TOKEN=$(echo $KC_RESPONSE| jq -r .access_token) KC_ID_TOKEN=$(echo $KC_RESPONSE| jq -r .id_token) KC_REFRESH_TOKEN=$(echo $KC_RESPONSE| jq -r .refresh_token) * Trying 127.0.0.1... % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 0 0 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0* Connected to localhost (127.0.0.1) port 8081 (#0) > POST /auth/realms/otp-validation-test/protocol/openid-connect/token HTTP/1.1 > Host: localhost:8081 > User-Agent: curl/7.45.0 > Accept: */* > Content-Length: 122 > Content-Type: application/x-www-form-urlencoded > } [122 bytes data] * upload completely sent off: 122 out of 122 bytes < HTTP/1.1 200 OK < Connection: keep-alive < Content-Type: application/json < Content-Length: 3713 < Date: Thu, 10 Nov 2016 20:32:16 GMT < { [3713 bytes data] # We got an acces token ... now lets try to validate a wrong OTP code curl -v \ -H "Authorization: Bearer $KC_ACCESS_TOKEN" \ -H "Content-Type: application/json" \ -d '[{"type":"totp", "value":"24861"}]' \ $KC_URL/realms/$KC_REALM/credential-validation * Trying 127.0.0.1... * Connected to localhost (127.0.0.1) port 8081 (#0) > POST /auth/realms/otp-validation-test/credential-validation HTTP/1.1 > Host: localhost:8081 > User-Agent: curl/7.45.0 > Accept: */* > Authorization: Bearer eyJhb...EW3Q > Content-Type: application/json > Content-Length: 34 > * upload completely sent off: 34 out of 34 bytes < HTTP/1.1 400 Bad Request < Connection: keep-alive < Content-Length: 0 < Date: Thu, 10 Nov 2016 20:30:42 GMT < * Connection #0 to host localhost left intact # Let's try a currently valid OTP code curl -v \ -H "Authorization: Bearer $KC_ACCESS_TOKEN" \ -H "Content-Type: application/json" \ -d '[{"type":"totp", "value":"949784"}]' \ $KC_URL/realms/$KC_REALM/credential-validation * Trying 127.0.0.1... * Connected to localhost (127.0.0.1) port 8081 (#0) > POST /auth/realms/otp-validation-test/credential-validation HTTP/1.1 > Host: localhost:8081 > User-Agent: curl/7.45.0 > Accept: */* > Authorization: Bearer eyJhb...EW3Q > Content-Type: application/json > Content-Length: 35 > * upload completely sent off: 35 out of 35 bytes < HTTP/1.1 200 OK < Connection: keep-alive < Content-Length: 0 < Date: Thu, 10 Nov 2016 20:34:11 GMT < * Connection #0 to host localhost left intact Cheers, Thomas 2016-11-10 14:27 GMT+01:00 Bill Burke <bburke(a)redhat.com&gt;: > Should be generic and not specific to a credential type.
