IMPORTANT: If you are asked to sign up to Universal Jobmatch on Monday at your Jobcentre or Work Programme Provider, it is Voluntary.
“Jobcentre Plus customers (including potential jobseekers) will not be mandated to register and create a profile.”

You do not have to create a Universal Jobmatch Account nor do you have to sign any forms relating to Universal Jobmatch.
Universal Jobmatch is a new online job posting and matching service that has been created by Monster.com for the Department for Work and Pensions. Universal Jobmatch (UJ) will allow monitoring of a claimant's Jobsearch activity, which could lead to sanctions. Also, UJ allows the sharing of your personal information with employers.
Monster.com have also been involved in several instances of personal information theft.
Whilst UJ is still voluntary —there may be plans to make it mandatory in the future—, you can opt out of the service and protect your data & privacy.
UPDATE: You could be given a Jobseeker’s Direction to register with UJ, even so you do not need to give permission (consent) for DWP to access your account.
