How to authenticate with JIRA Service Desk (on prem) using Oauth 2.0

[Service Account]

Is there any document to get the access token for JIRA Service Desk (on premise) using Oauth 2.0 method.

Hi, 
With the on-prem, I have a slight doubt that there's no token to Jira Service Management (Service Desk). You may check with https://github.com/sjbotha/jira-jwt-authenticator/ wherein an token gets associated.

For Jira Server users that want to create a REST API token, I would actually recommend checking out the Jira Server Devleoper page on OAuth.  This is the recommended method for authenticating REST requests against Jira.
