Force login without password

[monchu]

Hi All,

From API form I'm sending messages to a tradespersons group offering them a job via email. Each tradesperson has its own user name and password.

Once a tradesperson receive the email, I would like them to be able to click a link with form url to fill for job acceptance and fill other fields as well.

Is it possible to use $session->forceLogin($user) method  for this purpose? Or is there any method that I can use in my message body?

Not all tradesperson familiar to login and fill in password, so if just click the link from email and straightforward filling a form will be much easier for them

Thank you
