What is the usage of Access Token and Access Token Secret?


I have just started using Twitter API.
I started with application only authentication which a bearer token is returned.
(Oh meanwhile! How long the bearer token remains valid?)
I would like to know so how Access Token and Access Token Secret are useful? (In process of getting bearer token, Only Consumer Key and Consumer Secret were needed)


Hello Amir! Thank’s for visiting the forums.

Access tokens are not explicitly expired. An access token will be invalidated if a user explicitly revokes an application in their Twitter account settings, or if Twitter suspends an application. If an application is suspended, there will be a note in the Twitter app dashboard stating that it has been suspended.

Check out this helpful guide that shows how to generate a bearer token for your oAuth: Bearer Token
