Autofill functionality on Android devices stores frequently entered information, such as usernames, passwords, addresses, and credit card details, to expedite form completion across various apps and websites. This data is saved locally and can be accessed by the operating system’s autofill services when a matching field is detected. For example, when accessing a website requesting login credentials, the autofill service can suggest the previously saved username and password, minimizing manual input.
Managing stored autofill data is important for security and privacy. Over time, outdated or inaccurate information might be saved, necessitating its removal. Moreover, regularly clearing autofill data enhances security by mitigating the risk of unauthorized access to sensitive information if the device is compromised. Historically, manual deletion was the only option; however, Android has evolved to provide more streamlined methods for this purpose.
