Login using API Token
You can log into the Cloud Jira Accounts using API Token.
Perform the following steps to create an API token for your Atlassian account:
Under the API tokens section, click the Create API token to generate the API token.
Copy the API token.

Note
For security reasons, it is not possible to view the token after closing the creation dialog. If necessary, create a new token.
You should store the token securely, just like a password.
