Avoid getting locked out

Why this matters​

If you enable 2-Step Verification on your LuxID Account - which we strongly recommend - you need a second factor every time you sign in. But what happens if you lose your phone, change your number, or can't access your authenticator app?

Without a backup option, you could be locked out of your account and all the LuxID Partner services connected to it.

Set up multiple 2-Step Verification options​

The best way to avoid a lockout is to register more than one 2-Step Verification method. LuxID allows you to add multiple options, so if one is unavailable you can fall back to another.

For example, you could set up:

  • Two phone numbers - Your primary number and a second one (e.g., a work phone or a family member's number). Each number must be validated.
  • An authenticator app and a phone number - If you lose your phone, you can still receive a one-time code on another number. If your number changes, you can still use the authenticator app.
  • A passkey and a phone number - Your passkey works even without network coverage, while the phone number serves as a backup.
  • A LuxTrust certificate and a phone number - If you have linked your LuxID Account with LuxTrust, your LuxTrust certificate can serve as an additional authentication method alongside your other 2-Step Verification options.

To manage your 2-Step Verification options, go to account.luxid.lu (opens in a new tab) > Security > 2-Step Verification.

Keep your contact information current​

If you change your phone number, update it in your LuxID Account before deactivating the old number, or temporarily deactivate the 2-Step Verification method linked to that number. If your old number is your only 2-Step Verification method and you can no longer receive codes on it, you will not be able to sign in.

To update your phone number, go to account.luxid.lu (opens in a new tab) > Account. For the full walkthrough of switching to a new phone without losing access, see Change the phone number on your account and how it's used.

What to do if you are locked out​

If you have lost access to all your 2-Step Verification methods and cannot sign in:

  • If you have a passkey registered on another device, try signing in from that device.
  • Contact LuxID support for assistance. You will need to verify your identity before access can be restored.
