You can link a digital identity to your LuxID Account through LuxTrust. A linked digital identity provides identity-proofed authentication, adding a stronger layer of security to your account and promoting it to LuxID Verified.

What is LuxTrust?

LuxTrust is Luxembourg's trusted identity-proofing provider. Through LuxTrust, you can link an eIDAS-compatible digital identity to your LuxID Account - for example a Luxembourgish eID, a Smartcard, LuxTrust Scan, a Signing Stick, or LuxTrust Mobile. Once linked, you can use it for identity verification when performing sensitive actions or signing in to LuxID Partner applications that require a higher level of assurance. See LuxTrust (opens in a new tab) for more about these products.

Link a digital identity to your LuxID Account

1. Go to your LuxID Account (opens in a new tab) and open the Account tab.
2. Under Digital identities, open Digital identity service.
3. Select Add a digital identity, enter a name (alias) for it, then select Confirm.
4. Choose your device - Luxembourgish eID, Smartcard, LuxTrust Scan, Signing Stick, or LuxTrust Mobile - and follow the on-screen instructions from LuxTrust to finish linking.

Remove a linked digital identity

1. Go to your LuxID Account (opens in a new tab) and open the Account tab.
2. Under Digital identities, open Digital identity service.
3. Select the digital identity you want to remove and confirm the removal.

Renew or replace your digital identity

LuxTrust products do not last forever. A Smartcard, Signing Stick or certificate has an expiry date, and when it is renewed, replaced after loss or damage, or reissued, the new one is a different credential. Your LuxID Account does not follow that change on its own: it stays linked to the old identity, which no longer works.

If you use your digital identity for 2-Step Verification, this is the moment an account can lock you out. Signs that it has happened include an error such as "Licence invalid" during sign-in, or the LuxTrust step simply never confirming.

Do this before the old one stops working

While your current digital identity still works:

1. Sign in to your LuxID Account (opens in a new tab) and link the new digital identity, following the steps above.
2. Enable it for 2-Step Verification if you use your digital identity as a second step.
3. Only then remove the old digital identity.

tip

Keep a second, independent 2-Step Verification method - an authenticator app or a passkey - alongside your digital identity. A renewal, an expiry or a lost card then becomes an inconvenience rather than a lockout. See 2-Step Verification.

If the old one has already expired

If your previous digital identity has expired or been deactivated and you can no longer complete sign-in:

• If you have another 2-Step Verification method, sign in with it, then remove the old digital identity and link the new one.
• If the digital identity was your only second factor, you cannot do this yourself. Contact LuxID support from the email address registered to your account, and ask for the digital identity to be removed as a verification method. You can then sign in with your password and link the new one.

LuxTrust support is separate

LuxID can unlink a digital identity from your LuxID Account, but it cannot renew, replace or troubleshoot the LuxTrust product itself. For the card, token or app, contact LuxTrust (opens in a new tab) directly.

Use your linked digital identity for verification

When you perform a sensitive action within your LuxID Account (such as changing your password), you may be asked to verify your identity using your linked digital identity. This makes it much harder for an attacker to impersonate you.

Use your digital identity for 2-Step Verification

You can also use a linked digital identity as a second step when you sign in, alongside your password:

1. Go to your LuxID Account (opens in a new tab), open the Account tab, then Digital identities > Digital identity service.
2. Select Edit next to your digital identity.
3. Tick Enable this digital identity for two-factor authentication, then select Confirm.

Coming soon

We are working on letting you use a linked digital identity to recover access to your account - for example if you forget your password and have also lost access to your mailbox. This is planned for a future update.

What if you do not have LuxTrust?

Identity-proofing products like LuxTrust are mainly aimed at people who live in Luxembourg. If you work in Luxembourg but live across the border - for example as a cross-border commuter - you may not have a LuxTrust identity or a Luxembourgish eID.

For these situations, LuxID is preparing to support a future EU-wide digital identity wallet. Every EU country will offer this wallet to its citizens and residents, and a wallet issued in one country will be recognised across the whole EU. LuxID intends to support it as soon as it becomes available, so you will be able to reach a higher level of assurance even without LuxTrust.

How your information is protected

When you link a digital identity, LuxID stores only the information necessary to verify your identity. Your data is processed in accordance with the LuxID Terms and Conditions (opens in a new tab) and applicable data protection regulations. POST Luxembourg, as the data controller, ensures your personal data is handled securely.
