Issues found while testing -

1.Text should 'forgot password' instead of 'forgotten password'
2.In forgot password page, if user enter invalid user, no error is shown. Just page refreshes.
3.On reset password received below error on UI in case user clicks 2nd time on reset link & try tp reset password. .

• success 0 errormsg "name 'MessageType' is not defined"info ""result null data null.
  4.Unable to change password after login , 'name 'internal_server is not defined' error.
  5.Clicking setup MFA first time gives error - Something went wrong. (I guess incorrect redirection).After refesh able to setup MFA with email
  6.Unable to change password, 'name 'bad_request is not defined' error if user enters same password as old.
  7.Now the tab title is login for pgAdmin page. expected title should pgAdmin.
