Hi,
On my bank login page: https://clients.boursorama.com/connexion/
Filling the identifiant does not work, I get the message: “Unable to auto-fill the selected item on this page. Copy and paste the information instead.”
I have read this doc about custom field, I now fully understand how to get the name.
I am not happy with the fact that I have a duplication of this bank id (in username and in form_clientNumber):
Yes it can. The details are documented in the links I have provided to you multiple times above:
Linked: Field value is linked to the item’s Username or Password. Given the right field name, Linked custom fields can be used to solve issues where your Browser Extension can’t auto-fill usernames and passwords for a particular site (learn more).
