Maybe a stupid question because I am surrounded by professionals.

Is it possible to transfer username and password to a other contract?

Situation: For some services we use a token login (username, password and token). For other services we only use username and password field.
Is it possible to FormFill or transfer the username and password to the token login page?
When a user is already logged in and token authentication is required for a other service then the user has to fill again the username and password fields.
