Description
The autofill functionality in the web browser allows the user to complete a form that contains sensitive information, such as personally identifiable information (PII), without previous knowledge of the information. By allowing the use of autofill functionality, an adversary who learns a user's Microsoft Android 11 device password, or who otherwise is able to unlock the device, may be able to further breach other systems by relying on the autofill feature to provide information unknown to the adversary. By disabling the autofill functionality, the risk of an adversary gaining further information about the device's user or compromising other systems is significantly mitigated.
