How do I configure ccleaner to keep my saved logins without having to login again using ccleaner
If you are using Custom Clean then untick 'Session' for the browser.
Clearing the browser session logs you out of websites.
Also note that some websites still use a cookie to store your login status, if you are using one of those sites then you will need to either:
Put that cookie in 'Cookies to keep' in the CCleaner Options.
or do a scan in Health Check, click on 'Privacy' and then 'Manage allowed websites' to add the website to the keeplist.
