Like Google Authenticator, this also generates a time-dependent 6 digit OTP login code but unlike Google Authenticator, it also provides multi-device support, is also available as a browser extension and has encrypted recovery backups.

Why to use OTP login codes as 2FA?

Using only username and passwords for authentication during login on your WordPress website leaves your website more vulnerable and increases the risk of attacks. The problems encountered by static passwords, especially those created by the user happen to be two-fold. Firstly, they tend to be weak. Secondly, they tend to be reused across multiple websites. The OTP login codes as 2FA act as an additional layer of security on top of the credentials already being used. Since these codes are auto-generated in real-time, they solve both the issues mentioned above. They are auto-generated in real-time and therefore neither require the user to remember a complex passwords nor carry the risk of the same OTP login codes being used by the same user across multiple websites. The combination of these attributes, bolsters your WordPress website’s security and makes it impervious to cyber attacks.
