Can OAuth 2.0 authorise web forms like create screen in Jira Cloud

[Mohamad Alhajj - Infosysta]

Hi There,

We are used to display Jira Create screen in an Outlook plugin using web forms, currently, for a cloud solution, we depend on the cookies present after user authentication.

But we checked that Cookie and Basic Auth will be removed soon, so we are migrating to OAuth 2.0, but we noticed that it doesn't authenticate Jira web pages as Basic and Cookie does.

Is there something missing that we're doing or OAuth 2.0 doesn't support web forms?

if OAuth 2.0 doesn't support web form what other methods we can use to authenticate Jira Cloud web page in webview.
