Password and RSA Token fields

Hello, 

This is a screenshot of the fields I must fill in. If it does not show up it is a "Password" field above an "RSA Token" field. 

I must obtain the RSA Token passcode from the RSA app and enter it manually.

This is the problem:

When I use the 1P extension to autofill the password, it autofills the RSA field instead of the Password field. Highly annoying so I would be grateful for any suggestions. 

This is an iFrame which is why I am using the 1P extension to begin with. When I use MS Edge PW manager it autofills the correct password field so I guess I could use Edge PW manager just for inline webpages and 1P for everything else but I would prefer to use one or the other. (I disabled Edge PW manager when I started using 1P - does anyone have experience using both?)

The password for the above field is the same as the password for the main webpage. Ideally it would just autofill but I understand there is a security reason preventing this. I understand MS Edge PW manager does not have the same security issues because it created the browser and can handle tricky field detection better than 3rd party apps. 

Thank you.
