How to redact username password details on client browser when building MVC 5 application

Question

I have built an MVC application and I am using its standard authentication code generated by the template. The configuration looks like:

        public void ConfigureAuth(IAppBuilder app)
        {
            app.CreatePerOwinContext(ApplicationDbContext.Create);
            app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);
            app.CreatePerOwinContext<ApplicationSignInManager>(ApplicationSignInManager.Create);

            app.UseCookieAuthentication(new CookieAuthenticationOptions
            {
                ExpireTimeSpan = TimeSpan.FromDays(14),
                AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
                LoginPath = new PathString("/Account/Login"),
                SlidingExpiration = true,
                Provider = new CookieAuthenticationProvider
                {
                    OnValidateIdentity = SecurityStampValidator
                   .OnValidateIdentity<ApplicationUserManager, ApplicationUser>(TimeSpan.FromMinutes(30), 
                    (manager, user) => user.GenerateUserIdentityAsync(manager))
                }
            });

            app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);
            app.UseTwoFactorSignInCookie(DefaultAuthenticationTypes.TwoFactorCookie, TimeSpan.FromMinutes(5));
            app.UseTwoFactorRememberBrowserCookie(DefaultAuthenticationTypes.TwoFactorRememberBrowserCookie);
        }

The problem is that when I have logged in if I use Chrome tools and look in the payload tab for the Account/Login?ReturnUrl=mysite.com/somepage, I see both the username and password in plain text.

Is there a way to redact this information? or even better not have it? or is this standard approach?
