ProxyIdP offers a more secure way of authentication on top of passwords – the so-called Multi-Factor Authentication (MFA). Once activated, an additional form of authentication is required in addition to the required password, for example in the form of a verification code. This function makes it more difficult for potential attackers to misuse someone else’s account.
