8. Two-step security
Two-step security adds a second check after your password: a six-digit code from an authenticator app on your phone. DFFMS also gives you recovery codes and, for some roles, passkeys.
Who can do it: every staff member, for their own account. The Platform Super Administrator can make two-step security mandatory for all staff (section 11).
Before you start
- Install an authenticator app on your phone. Any standard authenticator app works.
- Keep your phone with you during setup.
- Have a safe place ready for your recovery codes. Do not store them on the same phone, or in a shared document.
8.1 Set up an authenticator app
- Sign in. If prompted, go to Account security. You can also open it from the profile menu (click your name, then Account security).
- Read the heading Secure your account.
- In Current password, type your password.
- Click Begin authenticator setup.
- The screen shows:
- a setup key (a long text code). Click the copy button labelled Copy authenticator setup key to copy it.
- a QR code. Use this instead of the key if you prefer.
- In your authenticator app, choose Add account (or the plus sign). Then either:
- scan the QR code on the screen, or
- choose Enter a setup key and paste the key.
- The app starts showing six-digit codes that change every 30 seconds.
- Back in DFFMS, under Single-use recovery codes, copy or write down every code. Store them in an approved secure location.
- Tick I saved these recovery codes in an approved secure location.
- In Six-digit verification code, type the code now showing in your app.
- Click Verify authenticator. The screen shows Authenticator verified.
8.2 Recovery codes
- Recovery codes are for when you cannot get a code from your phone.
- Each code works only once.
- Store them offline, in a safe place. Treat them like cash.
- If you use a code, make a fresh set as soon as you can.
Common problems
- The setup key was pasted into a chat or email. Treat the old authenticator setup as exposed. Tell your administrator. Set up a new authenticator from a clean start.
- You lost your phone. Use a recovery code to sign in. Then set up a new authenticator app from Account security.
- The button is greyed out. You must tick the box for the recovery codes first.
8.3 Passkeys
A passkey is a sign-in method stored on your device, such as a fingerprint or face unlock. It is harder to fake than a password.
- The Platform Super Administrator must register a device passkey when two-step security is mandatory. The page says: Platform Super Administrators must also register a phishing-resistant device passkey.
- Other staff can add a passkey from the same screen if it is offered.
- To add one, click Register this device passkey (or the passkey button on Account security) and follow your device prompts.
- Register a passkey on each device you use to sign in.
Common problems
- The passkey prompt does not appear. Check you are on the DFFMS address in your browser, and that your device allows passkeys.
- You see "Setup interrupted". Your secure session may have ended. Sign in again and start from Account security.
8.4 Mandatory two-step security
- By default, two-step security is off for general portal access.
- The Platform Super Administrator can turn on Require MFA before staff portal access in the Security centre. Then every staff member must set up an authenticator.
- Some actions always need two-step security, even when the policy is off. See section 10.
