@seednextsrl you typically don't use the access token as a login password.

The access token is what you present to other applications as proof that someone has logged in.

There are a few FusionAuth APIs you can call and present the access token as a means of authentication. They are marked with a little blue person.

Here's more about API authentication: https://fusionauth.io/docs/v1/tech/apis/authentication

Here's an example of an API which uses a JWT to authenticate: https://fusionauth.io/docs/v1/tech/apis/users#retrieve-a-user (scroll to the "Retrieve a User using a JWT" section).

@chirag have you seen these? https://fusionauth.io/learn/expert-advice/authentication/login-authentication-workflows/

Reviewing them and mapping your use case on to them may be helpful.

Thanks for your feedback!
