Autofill allows form fields online to be automatically populated with your relevant information. If you use password autofill – like password managers provide – your username and password are automatically filled in when you visit sites you’ve saved.
For example, if you do online banking, every time you visit your bank website, your username and password will automatically populate in the correct fields – so you can log in with one click.
But autofill doesn’t stop at passwords. You can also autofill addresses, credit card information and more.
