Set up strong authentication

If a sender requires a passkey or an authenticator app for their tasks, you receive an invitation by e-mail beforehand. With the link in it, you set this up, without an account. After that, you open protected tasks with your device.

  1. Click the link in the invitation. Strong authentication opens for your e-mail address. At the top it shows what the sender requires (Required: …).
  2. For a passkey: under Passkeys, click Add passkey, optionally enter a name, click Create passkey and confirm with your fingerprint, face or device PIN.
  3. For an authenticator app: next to Authenticator app, click Set up, scan the QR code with the app and enter the 6-digit code. Click Confirm.
  4. Keep the Recovery codes in a safe place and tick I have saved my recovery codes.
  5. Click Done.

For the next protected task, you confirm with it, see Open a protected task.

Lost device

If your phone is gone or the passkey has been deleted, set everything up again.

Strong authentication page with sign-in and Lost your authenticator or passkey?
  1. Open the link from your earlier invitation. Because it has already been used, actaSIGN shows a message and, below it, the form for resetting. If you are a member of an organization, you can sign in instead.
  2. Under Lost your authenticator or passkey?, enter your e-mail address.
  3. Click Send reset link. You receive an e-mail with a new link and use it to set everything up again.

If you have a recovery code, you can also open a task with it. After that, you must set up your passkey or app again.

Good to know

Section titled “Good to know”
  • Done is only possible once everything the sender requires is set up.
  • The link from the invitation works only once. If you have already used it, actaSIGN reports: This link was already used. In that case, request a reset link below.
  • An expired link can no longer be used. Request a new one or ask the sender for a new invitation.
  • Each recovery code works once. If you use one, you lose all factors you set up and set them up again.
  • If you are a member of an organization, you find the same setting in the menu, see Strong authentication in your profile.
