The European Digital Identity Wallet, or EUDI Wallet, is intended to let people carry identity information and verifiable documents such as driver’s licenses, diplomas, or professional qualifications on their phones and present them in online and in-person transactions. Under the European Commission’s timeline, member states are expected to provide at least one wallet by the end of 2026. However, the appearance of a wallet in an app store does not mean it will become usable in every country and for every service on the same day. National implementations, document issuers, and services requesting wallet data may become available at different rates.
The subject is also relevant to people living in Türkiye. Anyone studying, working, traveling, or conducting business in the EU may encounter the wallet. Still, an app is not necessarily official simply because its name contains “EU,” “eID,” or “European Wallet.” Before installing it, the safest starting point is to follow the app-store link from the website of the country’s authorized public institution.
Understand what the wallet changes
Under the traditional approach, you send an organization your entire identity card or a scanned copy. That copy may also reveal information unnecessary for the transaction, such as your name, photograph, date of birth, and document number. The EUDI Wallet approach aims to let you share specific attributes based on the request. For example, if a service only wants confirmation that you meet an age threshold, it may not need your complete date of birth or home address. This is known as “selective disclosure.”
This feature is not an automatic guarantee of privacy. Users must still read the wallet’s approval screen carefully to see which organization wants which information and for what purpose. It would be unusual for a movie ticket service to request proof of professional qualifications, a full address, or an identity number. Reject unnecessary requests, and check the service’s explanation and official support channel.
Verify the official wallet
Do not install the app through an advertising link, an APK file sent in a message, or an imitation website shown in search results. Because the publisher’s name alone is not sufficient, open the link from the domain of the authorized national institution. Compare the developer information in the app store, the domain hosting the privacy policy, and the update history. Do not import identity documents until you have installed your phone’s operating-system and security updates.
During initial setup, read how the wallet uses the device lock, biometrics, and recovery methods. Replace an easy-to-guess screen-lock code and enable biometrics so that a code observed over your shoulder is not your only line of defense. If the wallet asks you to create a recovery code, do not leave it as a screenshot on the same phone. Choose a printed copy stored securely or a suitable password manager instead.
A four-question test for every data request
Before approving a request, match the displayed name of the requesting organization with the service you are visiting. Then ask how each requested attribute relates to the purpose of the transaction. Check whether sharing is valid for a single transaction or for a specified period. Finally, find out how the data will be stored after it is transferred to the organization and where a deletion request should be sent.
The wallet’s support for selective disclosure does not mean that the other party cannot retain the data it receives indefinitely. European regulations establish strong principles for data minimization and user control. Even so, the life cycle of personal data transferred outside the wallet depends on the service’s legal obligations and technical implementation. After completing a transaction, therefore, review not only the wallet but also the privacy and deletion options in your account with the service.
Take care with QR codes and in-person verification
A QR code displayed at a counter may send a data request to the wallet. Before scanning it, make sure the counter really belongs to the organization with which you are conducting the transaction. Ask a staff member about labels that appear to have been added later, have a different color, or have peeling edges. Stop the transaction if the organization name on the wallet screen does not match the name you expect. A staff member saying that “you have to accept everything” is no reason to avoid questioning unnecessary attributes shown on the screen.
Outside the wallet’s normal approval screen, do not enter a PIN, banking password, or recovery key on a page opened in the browser. Check the web address that initiated the authentication request separately. Do not approve a wallet notification received during a phone call in which you are being rushed. End the call and dial the organization’s official number yourself.
Review the transaction history regularly
Use the wallet’s privacy dashboard or transaction logs to check which attributes were presented to which organization and when. If you see a transaction you do not recognize, do more than take a screenshot. If an option to export the log details securely is available, use it and report the transaction to wallet support and the relevant service. Features for reporting a suspicious data request to the competent data protection authority may vary by national implementation.
Perform a brief monthly review: check unused documents, connected services, active sessions, and pending updates. Deleting a document from the wallet may not automatically delete it from organizations that previously received it. Submit a separate data deletion request if necessary.
A plan for a lost phone
Enable remote location and locking before your phone is lost, and keep the recovery information for your device account up to date. Make a note of the wallet provider’s process for lost devices, suspension, and transfer to a new phone. If the phone is lost, lock the device remotely first. Then use the wallet provider’s official channel to follow the steps for suspending the wallet instance or identity credentials. Protecting the mobile line is important, but disabling the SIM alone does not necessarily deactivate the wallet on the device.
When moving to a new phone, do not immediately reset the old device. Confirm that the documents have been successfully issued to the new wallet, that you can access the transaction logs, and that the old wallet has been revoked. If you will rely on the wallet for a business or cross-border transaction, prepare offline-use options, backup documents, and support numbers before traveling.
The healthiest approach is to view a digital identity wallet not as a tool for “sharing everything with one tap,” but as a document vault that provides the smallest possible amount of data in every transaction. When installation from an official source, strong device security, careful approval, and regular log reviews are used together, the convenience can be enjoyed without turning into a loss of privacy.
