What happens to saved passwords when you clear your cache

You may have had the experience of clearing your browsing history and cache and then discovering that your browser logged you out of your favorite websites. If you saved passwords in your browser so you could automatically log in to certain sites, clearing your cache can clear your passwords as well.

Happily, Apple has a solution to this problem. If you use iCloud, check your iCloud settings on your phone or computer. Make sure that you've checked the box for Safari.

Make sure the Safari box is on under iCloud to retain your passwords in your keychain.

As long as this box is checked, any passwords you save through your browser will stay safe in your keychain.
