How to prevent user form entering password to next to password field?

Being long time internet users I tend to fill forms barely looking at field labels, especially if it is as common and seemingly predictable as registration form. It often leads me into entering password into the field which was not intended for that. I’m guessing not the only one having this habit.
The examples below appear to me as violations of POLA principle and lead users to errors with quite serious security implications: password can be displayed somewhere in the UI, it is likely to be stored in open form, it will be as autocomplete suggestion in the browser.
How to keep users from retyping their password in the field which is not intended for that?
Broader question here is how to break user expectations and habits when they are not applicable and do no good. In other words, how to violate POLA correctly?

Error message- display in a Modal vs display in the form

Generally, in a forms, when some field is invalid, the error message shows next to the field. However I am not sure where/how to display errors that are not directly related to the fields.
We have a webapp for the employees of a company. We store a list of credit cards that belongs to employees of the company, to create an account in the site the employee needs to provide its credit card. Then after clicking on “submit” we perform the following validations:
-
If the credit card provided does not match to anyone in our list, we need to show an error message, something like: “Unable to Register Account, We’re sorry, but the information you provided does not match our records. You may contact us at XXXXXX”
-
The credit card allow us to know which features user is going to see. If the credit card provided belongs to an employee that do not have any features allowed, we show an error like: “Unable to Register Account, No features configured for you…. You may contact us at XXXX.”
My question is how to show those messages? In a modal or in the same form (maybe at the top of above the Submit button)
Thank you in advance!!
