Two factor authentication

An OTP secures the login to your account with a one-time password, generated with limited time validity by third-party applications on your mobile phone (such as the Google Authenticator Application).

Each time you sign in, you fill in a code number from your mobile phone.

You may connect only one device to your account.

The mobile app we've created (for Android and iOS) for securing mojeID account sign-in.

After downloading the Authenticator application to your mobile phone, you pair the phone with your account. When logging in, you check the code displayed in the application on your phone to make sure it matches the code on your computer screen, then click the button to sign in to your account. You do not need to type the code.

You may connect only one device to your account.

A security token with support for the FIDO2 protocol is a small device (with a USB connector) that can be associated with your mojeID account. Then, besides filling in your password, you have to confirm login to your account also by pressing a button on the token.

You may connect only one device to your account.

FIDO2 tokens can be purchased from online stores. The product specification must include the FIDO2 label. These tokens are compatible with the older U2F standard.
You may also find the generic designation FIDO2 U2F in token specification.
You can use terms such as  "fido2 usb" or "fido2 nfc" to search the internet.

You may connect only one token to your account.

It is an authentication hardware token for multi-factor authentication, providing secure login through a computer or laptop. It requires physical presence of the token and manual user interaction as in a button press to log in.

The security token works without the need to install software or drivers, the device acts like a USB keyboard. The user needs only a version of a browser that supports FIDO2 devices. The latest versions of Chrome, Firefox, Edge and Safari work well.

By using a security token, threats such as Man-in-the-Middle Attack and Phishing can be eliminated.

The security token does not serve as a memory drive; it is intended only for login. It should be plugged directly into the computer, not into the docking station. You may connect only one token to your account.
