Get access token from keycloak cookies after login

Getting advice
,
1

Hi,

I connected my frontend application with keycloak server. After I log in, I get redirected back to my frontend application and everything is great. Keycloak sets a few cookies to maintain SSO like:

KEYCLOAK_IDENTITY and KEYCLOAK_SESSION

I noticed that KEYCLOAK_IDENTITY has a JWT for a value. Can we use this JWT or the info it contains to get keycloak access/refresh token we would otherwise get from:

https://www.keycloak.org/docs/latest/securing_apps/#token-endpoint

e.g.

curl --request POST \
  --url https://.../auth/realms/test-realm/protocol/openid-connect/token \
  --header 'Content-Type: application/x-www-form-urlencoded' \
  --data client_id=test_client \
  --data grant_type=password \
  --data username=test_user \
  --data password=test_password

Any advice / guidance is appreciated.
