To access your pre-requisite test or test, you must be logged in to your EU Login account on the computer you will use for testing. Please keep in mind that you need full administrator rights on the computer or laptop you will use for testing; corporate-issued devices typically do not provide these privileges.

Nevertheless, you can access your EU Login account from multiple computers. However, regardless of which device you use, you must:

• enter your EU Login username and password, and
• complete the second authentication step using your registered second-factor authentication method. 

If your only second-factor authentication method is the ‘Trusted Platform’ on one device  (e.g. Windows Hello or Touch ID), you will only be able to sign in from that specific device. 

Therefore, we strongly recommend that you add at least one backup authentication method, for example:

• EU Login mobile app (recommended)
  You can install the app on your phone and use it to authenticate when signing in from another computer. For more information, please see: How to add a mobile device and EU login App.
• Security key (e.g. a USB key)
  If you already have one, you can also use it on different computers, provided they support it.

Your invitation letter contains your EU Login User ID, which is indicated at the top of the letter. 

If you are already logged in to EU Login with the correct User ID, open the TAO testing platform and click the white EU Login button to access the test environment. 

If you have problems accessing the EU Login account specified in your invitation letter, please contact the EU Login Helpdesk, which is best placed to assist with EU Login-related issues. For information on how to do so, consult the section “If you still cannot find a solution to your issue” towards the bottom of the EU Login common issues page.

If you are experiencing issues accessing the Single Candidate Portal or applying for a competition, please check the situations below.

1. If you receive the message: “No Trusted Platform or Security Key found”

This means that you have not yet configured a second-factor authentication method (trusted platform) for your EU Login account.

What to do:

• Log in to your EU Login account and go to your account settings (gear icon in the top-right corner next to your name). 
• Add a trusted platform by following the instructions on “How to add a trusted platform”. 
• If the issue persists, please contact the EU Login Helpdesk. 

2. If you experience issues with the EU Login Mobile App or QR code

What to do:

• Follow the instructions on “How to add a mobile device and EU Login App”. 
• If the issue persists, please contact the EU Login Helpdesk. 
• To avoid such issues, you may use a trusted platform as your second-factor authentication method instead. 

3. If you receive one of the following error messages:

• “Security constraints prevent access to the requested page - Single Candidate Portal” 
• “Logout successful. User not found.” 
• “OIDC auth code validation failed” 

This usually means that you need to create a new EU Login account.

What to do:
Create a new EU Login account using a different email address that has never been used for an EU Login account before. Please follow the instructions on “How to create a Single Candidate Portal account”.

4. If you receive a “Profile requirement notice” pop-up message as seen in the picture below

This means that your account was created using a third-party sign-in option such as eID (e.g. itsme, SPID, ROeID, DigiD), Facebook, or Google. Accounts created using third-party sign-in methods cannot be used to apply for EPSO competitions.

What to do:

• Create a new account following the instructions on “How to create a Single Candidate Portal account”. It is recommended to use a different web browser. 
• To request deletion of the account created using a third-party sign-in method (user IDs starting with “v00”), please contact the EU Login Helpdesk.

To check whether your EU Login account is correctly configured, go to your account settings, then proceed as follows:

• Log in to your account
• Click on the settings (gear icon) in the upper right corner next to your name.
  
  
   
• Select "My Account”. There you can find general information about your EU Login, including your unique Identifier and the email address associated with it.
   

1. A unique identifier starting with "v00" indicates that your account was created using a third-party sign-in option such as electronic identification (eID platforms like: itsme, SPID, ROeID, DigiD, MitID etc.), Facebook or Google. These accounts cannot be used for the Single Candidate Portal.
    
2. If you currently work for an EU institution or body, please refer to the EU Login instructions for EU internal staff.
    
3. If you have worked for an EU institution in the past, your EU Login is probably linked to an existing unique identifier.
   In this case, if you experience issues creating your Single candidate portal account, please create a new EU Login account using a different email address. You can verify the type of EU login in the “My Account” section of your EU login.
    
4. If you have not yet set up a second-factor authentication method (mobile device or trusted platform), your account is not ready to access the Single Candidate Portal. Please add a second-factor authentication method in your EU login profile. Please also read the instructions on how to add a trusted platform.
    

Ensure that the email address used to create your EU login is a private email address. Using a corporate email may result in loss of access to your EU Login and consequently to the Single Candidate Portal.

Open competitions (Single Candidate Portal)

If you are an EU staff member and your account was created using a corporate EU login, your personal data is imported from internal HR records (Sysper) and cannot be changed in the Single Candidate Portal.

If you are an external candidate and you created your account using your personal EU Login, you can request changes to your personal data via the “Contact us” menu in your account. All requests must be supported by an official document justifying the change.

Processing may take several days, so we kindly ask you not to submit multiple identical requests. You do not need to wait for the changes to be validated; you can go ahead and continue with your application/test booking.

Contract staff selection procedures (EPSO account)
Click on “Personal data” in your EPSO account and follow the instructions to edit your personal information.

To change your family name (surname), family name at birth, first name, date of birth, or citizenship, you must send a request with a copy of an official supporting document (e.g. passport, ID card, legal document) to EPSO-PERS-DATA@ec.europa.eu.

Once your request has been approved, the updated data will appear in your EPSO account.

Please note that requests may be refused if no supporting document is provided within five days.

Processing may take several days, so we kindly ask you not to submit multiple identical requests. You do not need to wait for the changes to be validated; you can go ahead and continue with your application/test booking.

Note that your validated new personal data will be taken into account for your validated applications.

In most cases, candidates cannot access their application(s) because they have created more than one Single Candidate Portal (SCP) account, linked to different EU Login accounts and they are trying to access their application(s) via the wrong SCP account. 

Follow the steps below to identify the correct account and regain access to your application.

Step1: Identify all the EU Login accounts linked to your email address(es)

• Retrieve the automatic email from the EU Login authentication service that was generated after the creation of your EU Login account.This email contains your User ID, which usually starts with “n00”.

If you cannot find this email:

• Go to: https://webgate.ec.europa.eu/cas
• Enter each of your email addresses and click “Next” to check whether an EU Login account exists for that address.
• If you do not remember your password, click “Lost your password?”
• If you have several email addresses, repeat this check for each one

Step 2: Once you have identified all your EU Login User IDs:

•  Log into the Single Candidate Portal using each User ID (not your email address) until you find the account that contains your application(s).
   

Remember that each EU Login User ID has its own password and second-factor authentication method. You must therefore use the password and second-factor authentication method associated with the User ID you are using to sign in.

Step 3:

If you still cannot find your application(s), but you still have access to at least one SCP account, please contact EPSO indicating: 

• all your EU Login User IDs and all your email addresses.

If you cannot access the SCP, please use the contact form on our website.

Important 

• Do not create a new EU Login account if you are having trouble finding your application.
• Do not use eID, Google or Facebook sign-in methods
• Do not delete any EU Login accounts. Deleted accounts will be permanently lost.
• For EU Login-related issues, contact the EU Login Helpdesk at Still need help? - European Union

It 's very important to keep a record of the User ID, second-factor authentication and the email address used for your SCP account.

If you are still having difficulty in logging into your account, contact EPSO support immediately. 

Please note that EPSO staff will never ask you for your password by email. You should always sign in via a secure connection indicated by a padlock icon.

In the past, all EPSO selection procedures were managed through the EPSO Account. EPSO is now gradually moving to a new platform: the Single Candidate Portal.

At present, different platforms and candidate accounts are used depending on the type of selection procedure:

• For open competitions published after 1 January 2025, candidates must use the Single Candidate Portal. 
• For open competitions published until 31 December 2024 and for contract staff selection procedures, candidates must continue to use the EPSO account until further notice.

Candidates may have more than one profile in the Single Candidate Portal. However, only one EPSO Account is allowed. Having more than one EPSO account may lead to exclusion from the selection procedure.

Candidates must ensure that they have access to the relevant candidate account and to the email account associated with it throughout the selection procedure, including until the publication of the reserve list.
