How MFA Works in Practice
Multi-factor authentication (MFA) is key to keeping systems safe. It uses many layers of security to stop unauthorized access. This makes it much harder for hackers to get in.
The MFA process has a few main steps:
- First, you log in with your usual username and password.
- Then, you get a signal to do more to prove who you are.
- Next, you use a second way to show you’re you, like a code sent to your phone.
- After that, you’re checked again and then you get in.
MFA can block up to 99.9% of hacking attempts. Companies that use MFA see a big drop in security threats. They report a 70% cut in phishing attacks. Multi-factor authentication transforms digital security by creating multiple barriers against unauthorized access.
There are many ways to use MFA, each with its own level of security. Some common methods include:
