The NoiPA portal has become an essential reference point for Italian Public Administration employees in recent years.
NoiPA is necessary as it allows you to access payslips, manage personal data, request loans, handle pension contributions, and access agreements in a digital and secure way.
With the growing number of available features and the increasing focus on data protection, an additional security layer has been introduced: the NoiPA OTP code.
In this complete guide, I will show you how to enable NoiPA OTP, what it is really used for, where to find it, how to generate a NoiPA OTP code through the app, what to do if the NoiPA OTP code does not work, and the quickest solutions to fix possible errors.
NoiPA OTP: what it is and what it’s for
The term OTP stands for one-time password. It is a temporary numeric code that changes with every use and is required as an additional verification step when performing sensitive operations on the NoiPA portal.
Not all actions require this system. For example:
- It is not needed just to view payslips or simple documents.
 - It is essential, however, for more sensitive operations such as modifying personal or salary data, activating agreements, joining pension funds, or requesting loans through NoiPA.
 
The NoiPA OTP code can only be used by those who log in with SPID or CIE level 2 credentials. It is not necessary for those using CIE level 3 or CNS, which already provide a higher authentication level.
Why NoiPA changed the OTP system
Until 2024, the OTP code was sent via SMS directly to the phone number linked to the user’s profile. While practical, this method was no longer considered secure or efficient.
From June 2024, the procedure has been updated:
- It is no longer possible to receive the OTP via SMS.
 - To access services, it is now necessary to enable NoiPA OTP through the official app, available on Android (including alternative stores for devices without Google services) and iOS.
 
Alternatively, those who do not wish to use the official app can use compatible authentication apps such as Google Authenticator, but only after the initial setup through NoiPA.
How to enable NoiPA OTP: step-by-step procedure
Here is the practical procedure to enable OTP on the official app:
- Download and open the NoiPA app
Find it in your device’s store (Google Play, App Store, or alternative Android stores). After installation, launch it. - Log in to your personal area
Select “Entra con SPID” or “Entra con CIE”. After authentication, you’ll be redirected to your reserved area. - Verify email and phone number
Go to Menu → Profile. Check that your email address and phone number are validated. If not, update them using the pencil icon and complete the verification via email link or SMS code. - Enable OTP reception
Still under the Profile section, tap on “Enable OTP code”. If you see “Re-enable OTP code”, it means you previously used SMS OTP and now need to configure it again with the app. - Create a security PIN
You will be asked to set a 6-digit numeric PIN. This will allow you to generate OTP codes in the future without logging in fully. - Confirm activation
Tap on Activate and wait for confirmation. At this point, the NoiPA OTP function is active. 
How to generate NoiPA OTP code
Once activated, you can finally generate your code. There are two options:
- From your personal area
Open the NoiPA app → Menu → Generate OTP code. - From the home screen
Without a full login, select Generate OTP code. In this case, you will need to confirm your identity with facial recognition, fingerprint, or your PIN. 
Each code has a limited validity (generally 30–60 seconds) and can only be used once.
Where to find the NoiPA OTP code
Many users ask: “Where do I find the NoiPA OTP code?”
The answer is simple: the code is no longer sent via SMS or email but is generated exclusively in the NoiPA app once the function has been activated.
If you have multiple devices, remember that the OTP will only be available on the one where you completed activation.
What to do if the NoiPA OTP code does not work
Even if you have correctly activated the service, sometimes the NoiPA OTP code may not work. The most common reasons are:
- Using a different device from the one registered: in this case, you must use the Re-enable OTP code function on the new device.
 - Expired code
OTPs have a short validity, so you must generate a new one. - Incorrect PIN
Entering the wrong PIN multiple times can temporarily block access. 
In each of these cases, the solution is simple: go back to the official NoiPA app and follow the on-screen instructions to reactivate the function or generate a valid new OTP.
How to request NoiPA OTP on a new device
If you change your smartphone, here’s the procedure:
- Install the NoiPA app on the new phone.
 - Log in to your personal area.
 - Go to Menu → Profile.
 - Tap on Re-enable OTP code.
 - Set a new PIN and confirm.
 
This way, the OTP code will be generated on the new device, automatically deactivating the old one.
Alternatives to the NoiPA OTP app
If you do not want to install the official app, you can use authentication apps such as Google Authenticator or Microsoft Authenticator. In this case:
- You must first enable OTP from the NoiPA portal.
 - Then link the account to the authentication app using a QR code or setup key.
 
This is especially useful for those who use multiple 2FA services and want to centralize them in a single app.
Security tips
Using the NoiPA OTP code increases security, but safety also depends on you. Some practical tips:
- Never share your PIN with anyone.
 - Do not save screenshots of the OTP: it is temporary and saving it could pose risks.
 - Regularly update the official NoiPA app to always have the most secure version.
 - Periodically check that your email and phone number are correctly linked.
 
In summary
The introduction of the NoiPA OTP system is an important step toward safer access to digital Public Administration services. While it may seem complicated at first, once activated, generating a code is simple and fast.
Now that you know how to enable NoiPA OTP, how to generate it, where to find it, and how to act in case of malfunctions, you can access the most sensitive NoiPA services with greater confidence and protection.
