Multi-Factor Authentication (MFA) is a security method that requires multiple forms of identification to access MyAcerta. In addition to a password, users can enable additional authentication methods to step up protection against unauthorised access.

If you have a MyAcerta account, we recommend activating your MFA via the login options function in MyAcerta.

Tip - You can combine different MFA methods for optimum ease of use and optimum security.
Even if you have multiple user profiles, you can choose how to optimise your security.

Here are the options for each login method:

Username / Password

• Combination is set by default when creating your profile
• There is a unique combination (with self-chosen password per user profile - ON number)

itsme®

• Can be enabled for one ON user profile
• If you want to set itsMe up for another profile when it has already been used, you need to disable this profile before re-enabling it on the desired profile.

eID

• Can be activated for one ON user profile
• If you want to set up eID for another profile when it has already been used, you need to disable this profile before re-enabling it on the desired profile.

Authenticator and Passkey

• Can be enabled for each of your ON user profiles (procedure below)

1. Enter your username. That can be either your e-mail address or your ON username.

2. Enter your password and log in.

Please check our FAQ: question 1. “I have forgotten my username”.

Security Level: 

Note: You can only link your itsMe to one of your user profiles. If you want to link your itsme account to another profile, follow these steps:
 

Disable:

• Log into the user profile on which your Itsme is currently active.
• Disable your itsme link in the settings of this profile.

Enable:

• Log into the desired user profile.

The first time you log in with itsme®, you need to link your Acerta account to your itsme® account. You only have to do this once. This is what you need to do:

1. Click on the “Log in with itsme®” button.

2. At that point, the familiar itsme® login procedure will start.

The itsMe screen opens, where you can enter the phone number you use for your itsMe account.  After entering your phone number, you can approve the request via the itsMe app.

3. After you have successfully completed the itsme® procedure, the system will ask for the details of the Acerta account you want to link. If you had previously linked your account, you will be taken straight to MyAcerta.

4. Enter your existing Acerta username and password here once. If you have multiple user accounts with Acerta, use the account for which you want to use itsme® in the future. Please note: Only one user account can be linked to itsme®.

After logging in, you will have access to myAcerta, and you will be able to log in directly with itsme® in the future.

! Please note: This functionality is only available if your organisation has an agreement and a technical integration in place with the Acerta platform. 

The first time you log in with your company account, you need to link your Acerta account to your company account. You only have to do this once. This is what you need to do:

1. Enter your professional e-mail address in the “Username” field and click on “Next”.

2. You will be redirected to the login page of your own organisation. After you have successfully logged in, the system will ask for the details of the Acerta account you want to link. If you had previously linked your account, you will be taken straight to your MyAcerta.

3. Enter your existing Acerta username and password here once. If you have multiple user accounts with Acerta, use the account that you want to use in the future via your company account. Only one user account can be linked to your company account.

Security Level:

Note: You can link your authenticator app to multiple user profiles, even when these already have another authentication method (itsMe / eID) enabled.
  Acerta recommends Microsoft’s authentication app, which can be downloaded from the Android or Apple app store.

1. To get started with multifactor authentication (MFA), you need an authentication app.

Acerta recommends: Microsoft Authenticator App

Android Google Play	Apple iOS

2. Go to the login options page, click on activate and follow the instructions.

3. After clicking 'enable', click 'start activation', then enter your password. 

4. Open the Microsoft authenticator app and scan the QR code via the Microsoft authenticator app.

5. Follow these steps:

• Click the '+' sign

• Click 'work - school account'

• Scan QR code

Type the (time-limited) code that appears on the Acerta screen.
Note: multiple Acerta ON profiles may appear here if you have already performed this activation for multiple profiles.

6. If you lose your smartphone, you can use these codes to ensure you can still log in. Each code can only be used once.

You will be redirected to the MyAcerta environment where you will see that Authenticator app is enabled.
(if desired, you can disable the option by hitting the 'disable' button)

Check whether passkeys are supported on your device.

Before you can use passkeys, you need to install another multifactor authentication method. That way, you can be sure you won’t lose access to your account.

Go to the login options page, click on activate and follow the instructions.
