Suggest Alternat option For Login in Jira From 3rd party Api

[Apeksha]

I am already using Api for Token base login ref-->> https://support.atlassian.com/atlassian-account/docs/manage-api-tokens-for-your-atlassian-account/  but now can any one suggest me other solution for Login and generate token    

Some issue with The API Token needed will be shared
with the Layer7 team, which will arrange the secure integration.
