Users can log into their Cloud Jira Accounts using API Token. The following are steps to create an API token for your Atlassian account.
Step 1. Log into https://id.atlassian.com/manage/api-tokens.
Step 2. Click on the Create API token button to generate the API token.
Step 3. Copy the API token.
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.
