Encrypt User id and Password for /api/v1/authn in OKTA Chrome Browser?

Hi Team,

We need your help. is there any way we can encrypt user name and password when we call the service /api/v1/authn this in chrome browser. We setup the application with trust using SAML 2.0 protocol in encryption setup.

The application will redirect to the OKTA login page and in the okta idp when we enter user id and password, when we do F12 or inspect in chrome browser, we can see the user id and password visible in plain text.

Please find the screen shots, customer wants to hide this user id and password.

OKTA Login

Password Visible

Thanks and Regards
