Is it possible to auth on JIRA API without server between client and Jira

[Deleted user]

I built a client application (angular) that allow to my team to create jira issue.

The user has to login with their jira credential (user and pw) on my app.
 
To post a issue on JIRA API I'm using basic auth on the request  header :
"Authorization: Basic XXXXXXXXX"

It worked well until we update JIRA and now basic auth not working anymore. 

What is the best solution to make my app work again ?

Should I implement OAuth but I need a server to manage the Jira OAuth logic or is there any other solution keep a simple client app to communicate with JIRA API ?

Hi @[deleted] ,

Maybe I misunderstood, but I don't think you can remove the server from this process: https://developer.atlassian.com/server/jira/platform/oauth/#:~:text=In%20Jira%2C%20a%20client%20is,the%20user's%20permissions%20in%20Jira.

I recommend to check in the Atlasian Developer Community as well: https://community.developer.atlassian.com/
