What is mobile push notification and why is it a popular method for two-factor authentication?

Mobile push notifications are increasingly being used as a second factor of authentication in multi-factor authentication (MFA) setups. The reason for this is that push notifications provide an additional layer of security beyond just a username and password.

With push notifications, a user would enter their username and password as the first factor, and then receive a notification on their mobile device as the second factor. The user would need to approve the push notification to complete the login process. This helps to ensure that only the legitimate user with access to the registered device is able to authenticate.

Push notifications are becoming a popular option for MFA because they are easy to use and readily available on most modern mobile devices. Push notifications can also be more convenient than other second factors of authentication, such as physical security keys, since they don't require the user to carry around an extra device.

However, it's important to keep in mind that push notifications are not foolproof and can still be vulnerable to certain types of attacks, such as phishing attacks that trick users into approving malicious notifications. Therefore, it's important to use push notifications in combination with other second factors of authentication for added security.
