Multi-Factor Authentication Options

Authentication App

This allows the User to re-set up the Two Factor Authenticator app for the user, such as when the User has a new phone and needs to add the Authenticator app to the new device.

For more information regarding how to do this, please refer to the section about resetting Two-Factor Authentication which can be found here.

Security Keys

If a User is looking for a hardware security solution instead of using an Authentication app, there are a variety of multi-factor authentication Hardware Security keys for use with PDK.io. While multi-factor security keys are more secure when used properly, hardware keys do have drawbacks as they can be relatively expensive, have limited operability with certain operating systems, or be incompatible with certain mobile devices.

To set up a security key for a hardware device, tap/click Set Up to add a hardware security key. If a hardware security key was previously added and needs to be removed, tap/click Disable.

SMS

All Users with Integrator permission are required to enter a phone number capable of receiving SMS (Short Message Service, or text) messages for use with multi-factor authentication.

SMS Authentication is only allowed for a single phone number per User, with the entered number displayed on the second line (blanked out for privacy in the image below).
