Multi-factor authentication (MFA) is an increasingly popular method for securing user accounts that requires users to provide two or more pieces of identifying information when logging into an application. This information can consist of unique verification links or codes sent to the user’s phone or email address, as well as time-based one-time passwords (TOTPs) generated by authenticator applications or hardware.

Testing uptime, response time, and other performance metrics in applications can take a few different shapes. One common technique is an approach known as synthetic monitoring. This form of performance monitoring doesn't rely on real users interacting with a service, and instead uses automated tools to mimic interactions. Then, the results are recorded and parsed just like other solutions.
