Enable or Disable Google Autofill auf Huawei
Google Autofill is a system-level service on Huawei phones running Android with EMUI. Once active, it reads saved entries from your Google account and inserts them into matching fields across apps and browsers: login names, passwords, addresses, and payment details.
This behavior is convenient for repeat logins but becomes a problem on shared devices or when a form shows the wrong stored entry. Disabling the service removes automatic suggestions everywhere, not just in one app, since it is a device-wide setting rather than a per-app permission.
To change it, open the following path:
Open the settings ➔ Tap on Privacy ➔ Tap on Advanced ➔ Tap on Autofill service from Google ➔ Tap on Continue and follow the instructions on the display
If you only want to stop autofill in a single browser, check that app's own settings first, since a browser-level autofill option can override or duplicate the system service. Turning off the Google service entirely means you will need to type login details manually everywhere until you switch it back on.
