Confluence records the number of failed logins attempts made against each user account. When the login attempts exceed a preset number, the user will prompted to authenticate using CAPTCHA until they successfully log in.
If you are a Confluence Administrator, you can manually set the failed login count for a user back to zero.
To reset the failed login count for a user:
- Choose the cog icon , then choose General Configuration under Confluence Administration
- Choose Manage Users in the left-hand panel.
- Search for the required user and click the user in the search results. The 'View User' screen will appear.
- Choose Reset Failed Login Count' for the user. The 'Current Failed Login Count' will be reset to 0.
