Hi jolo
You could try to start here:
If you are using KeePass, go to the section “Edit entry” dialog or if you use Kee Vault Entry Browser form settings.
Using these options you can create custom fields that will populate any aditional fields in your login forms.
I haven’t tried to create multiple fields: only had to use this setting to customise the field id and field name for the Amazon AWS login console throught KeeVault.
I think it should work just fine if you create another login field, for example: “identity” and configure the correc field t id and field name on it.
If you need more help finding these fields just ask!
