CCleaner is a popular system optimization tool that clears out temporary files, cookies, and browsing history to free up space and enhance privacy. When it comes to saved passwords, CCleaner typically does not delete them by default. However, there are certain circumstances where CCleaner may inadvertently remove saved passwords.

One of the key features of CCleaner is its ability to clean browsing data, which includes cookies. Cookies are small files that websites store on your computer to remember your preferences and login sessions. If you configure CCleaner to clean cookies, it may remove saved passwords associated with those cookies.

Additionally, if you use CCleaner's registry cleaner feature, it may delete registry entries that store password information. This can lead to saved passwords being lost or rendered ineffective.

To prevent CCleaner from deleting saved passwords, you can customize its settings to exclude certain types of data from being cleaned. Make sure to review the options in CCleaner and uncheck any settings that could potentially remove your passwords.

In conclusion, while CCleaner does not typically delete saved passwords, it is important to be cautious when using its cleaning features to avoid unintentional data loss. By understanding how CCleaner works and adjusting its settings accordingly, you can maintain the security of your saved passwords.
