You can also generate the access token from the CLI or an API.

For example:

IDCS_AT_PWD=$(curl "${CURL_FLAGS}" -u "$IDCS_CLIENT_ID:$IDCS_CLIENT_SECRET" $IDCS_URL/oauth2/v1/token -d "grant_type=password&scope=urn:opc:idm:__myscopes__&username=${IDCS_USERNAME}&password=${IDCS_PASSWORD}" | jq -r ".access_token")
