6 Best Security Keys



When securing user information, using app-based two-factor authentication on a smartphone is more successful than relying just on passwords.

Using physical two-factor authentication is the best approach to secure online accounts. Security keys offer an additional layer by allowing users access to services via a keypad or button instead of the standard software-based two-factor authentication that sends an email or text message to validate the user’s identification. This can offer a high level of protection without requiring a device to receive a code in the beam.
