In the first instance please click the "Forgotten Password" link on the Defence Gateway logon screen.

An email will be sent to the email address you set as your recovery email address. There will be a link inside of this email which will allow you to regain access to your account.  With the recent  introduction of Microsoft safe links, you will need to copy and paste the link into your Browser address bar to start the reset process. (Chrome is the preferred browser)

After this link is used a page will be opened where you can enter your security answer to your security question.

Also please ensure your SyOps is up to date otherwise this will stop you from getting online via DII/MODnet . The SPOC can help you with any issues you have with SyOps or BPS

If you have forgotten your Security Answer, no longer have access to your recovery email address or have tried too many times please raise a ticket.
