When SSO is supported, logs in but step fails as password isn't needed

## Describe the bug
When using the step "Given I am logged in to the '' app as ''" when single sign on is supported, the password tries to be put in but there is nowhere for it to be put in as no password is needed, so getting an error on object reference not set to an instance of an object.

## To reproduce

Logged in to VPN to support single sign on.
Ran test with step: Given I am logged in to the '' app as ''
Exception on object reference not set to an instance of an object.

## Expected behaviour
To log in successfully with SSO.
