At the moment there is no available option for disabling "Remember My Login on this computer" feature via the Admin console.
However, there is a feature request available.
As a workaround, one can make modification to the velocity file
login.vm. This would require a server restart nevertheless.
The steps required are as follow:
- Stop Confluence
- Go to your confluence install directory
- Locate the
<CONFLUENCE-INSTALL>/confluence/login.vmfile and make a back up copy
- Open the file. Locate the following code and comment it out.
- Save the file and restart Confluence
- Repeat the steps when you install a new version of Confluence
Note: The code above is already commented out.
