## Overview

After changing "token duration" settings on an Authlete service that has been issuing tokens, Authlete will:

* Preserve duration settings for tokens previously issued
* Apply the new duration settings for tokens to be issued after the change

This article explains how the settings affect access tokens and refresh tokens.

## Access Tokens

The new duration settings are to be applied on (re)issuing access tokens on token requests with various grant types including refresh token grant.\\

## Refresh Tokens

The change may affect refresh tokens based on "**Refresh Token Continuous Use**" settings.<img src="https://mintcdn.com/authlete/KNbgpS77nJg5j2Vw/img/kb/en/oauth-and-openid-connect/tokens/changing-token-durations_1.png?fit=max&auto=format&n=KNbgpS77nJg5j2Vw&q=85&s=b26d76e1fbe5c8b20b3255767a21ace5" alt="changing-token-durations_1" width="536" height="189" data-path="img/kb/en/oauth-and-openid-connect/tokens/changing-token-durations_1.png" />

*“Refresh Token Continuous Use” in “Token” tab*

* If "**Kept**" is selected

  * The new duration won't be effective until the existing refresh token is expired and reissued.\\

* If "**Not kept**" is selected

  * The new duration is effective for a new refresh token that is to be issued along with a new access token on refresh token grant (using the old refresh token).<img src="https://mintcdn.com/authlete/KNbgpS77nJg5j2Vw/img/kb/en/oauth-and-openid-connect/tokens/token-duration-3.png?fit=max&auto=format&n=KNbgpS77nJg5j2Vw&q=85&s=59275b78a104f4535b112ce7b1df350c" alt="token-duration-3" width="967" height="436" data-path="img/kb/en/oauth-and-openid-connect/tokens/token-duration-3.png" />
