# Generate AccessTokens

You must have SSI service secret key and KYC service secret key with you before proceeding to this step. 

In order to use APIs of your services, you need `accessToken` generated using your API secret keys. Generate accessToken by calling **Service Authentication API** using API secret keys. You might want to **implement an API** in your backend which will call **Service Authentication API** to generate accessTokens for SSI and KYC services, so that your API secrets are not exposed in your frontend or anywhere else.

Let's call these accessToken as `kycAccessToken` and `ssiAccessToken` for KYC service and SSI service respectively.

Once you have both `kycAccessToken` as well as `ssiAccessToken`you may now proceed to frontend integration of the KYC widget.
