No password is needed to logon to a Candidate Account.
Go to Candidate Account website and enter your e-mail address that has been used to create the account. Having entered the address you will be sent a link to login with a given e-mail address.
It is a secure solution as each account is linked with one e-mail address accessed only by the owner of the mailbox. Hence the link to logon to your account will be sent to your mailbox only. For additional security, the link to logon is one-off and only valid for 24 hours. Unless you make it available to anyone, only you can access the account.
Please remember not to forward the e-mail with the link.
