I am using Google 2 step verification for my email account, and every time I run CCleaner, I end up having to reënter the Google 2 step password, even though I told it to not require another verification for another 30 days. Thus, Ccleaner is obviously erasing something that the verification process is storing.
If anyone has any idea what that might be, and what I therefore should uncheck in Ccleaner, I would appreciate it.
Oddly enough,i have two email accounts with 2 step verification, and only one keeps asking for reverification.
The Cookies to Keep seemed to have worked. Didn't know that option was in there. CCleaner really has a ton of options - I generally haven't paid much attention to them so thanks for bringing this to my attention. You saved me some valuable time.
