Atlassian adds OAuth 2.0 two-legged credentials for service accounts

Atlassian Administration adds OAuth 2-Legged credentials as a service-account authentication option alongside API tokens in a combined credential menu.

Atlassian Cloudservice accountOAuth 2.02LOAPI token

Previous state

The service-account credential workflow exposed API-token credentials without the new OAuth 2LO option in the combined menu.

Current state

Administrators can select OAuth 2.0 or API token when creating credentials for a service account.

Who needs to care

Atlassian Cloud organization administrators and integrations that authenticate through service accounts.

What to do

Evaluate OAuth 2LO for new or rotating service-account credentials and retain existing API-token handling unless a separately evidenced migration is chosen.

What the source does not prove

The source adds an authentication option; it does not state that existing API tokens migrate, expire, revoke or become deprecated.
