There are a few apps that can turn existing iOS and Android devices into a 2FA, but two apps have risen to the top of our radar during the past few years, especially when it comes to authenticating via push notifications (via API callbacks for custom and supported applications): Microsoft Authenticator and Duo. SEE: Password breach: Why pop culture and passwords don’t mix (free PDF) (TechRepublic) By requiring a username, password and security prompt through supplying a 2FA rolling code or push notification, secure systems can ensure that a user’s device is with them when authenticating. One of the ways that security protocols can be ensured is by requiring two-factor authentication (2FA, also known as MFA or multi-factor authentication).

The enterprise world has seen increased security protocols since work from home has increased over the past few years. For more info, visit our Terms of Use page.

We compare the features and costs of two of the biggest players in this space, Duo and Microsoft Authenticator, and pit them head-to-head. Passwordless and MFA push-based security apps are becoming the norm in enterprises.
