Regarding the expiration time for Auth Token for Endpoint central on-prem

Regarding the expiration time for Auth Token for Endpoint central on-prem

Hi everyone, we are using Endpoint Central on-prem. We can see in the document the steps to generate the Auth Token: https://www.manageengine.com/products/desktop-central/api/.

However, the API doesn't mention when the Token expires. Does this token ever expire? Or can it be used for an indefinite time? 

Also, if I generate a new token, does the old token expires?
