Sometimes a login page will have an additional field on top of the username and password (ex. last name, account number). This is often the case with things like banks, insurance, or government accounts.

I usually use Bitwarden to populate the username and password, then fill in the other field manually. Turns out, you can autofill those fields too:

1. Right click in the field
2. Select Bitwarden > copy custom field name

Then enter that as the name for the custom field.

Up till now, I was using custom fields to store additional information about the webpage. This will make things easier :)
