What is multi-factor authentication?
Multi-factor authentication (MFA) adds an additional layer of safety to your accounts. Instead of relying on only one password, MFA needs you to verify your identity using two or more methods. These may include SMS code, authenticator apps or physical security keys.
MFA vs. two-factor authentication
Two-carcass certification (2fa) is a type of MFA that uses exactly two verification methods. On the other hand, MFA may include two or more factors. For example, a password may be required to log in to your bank and a code from an app-this is an MFA in action.
Which multi-factor authentication method is the best?
Not all websites and apps support all types of MFAs, so your choice may depend on what is available. Here is described how the main options compare:
- Physical Safety Key: These provide the highest security and are resistant to fishing and malware. However, they are less convenient and not universally supported. If you lose your key, you will need a backup method.
- SMS Text Message: SMS is easy to use and is widely supported, but it is at least safe. Hackers can prevent text messages or redirect, which can weaken this method.
- Authenticator Apps: These apps form balance between security and convenience. They are less likely to be hacked and working on most smartphones. However, not each service supports them, and you may need internet or cell service to use some features.

Why do banks use SMS for MFA?
Many banks use SMS for two-factor authentication as it is easy to install and works on any phone. However, SMS is not the safest method. Authenticator apps and physical security keys provide better protection against modern threats.
Is there a size-fit-all solution?
Unfortunately, there is no universal MFA solution for every account. The best approach is to use the strongest MFA method supporting each service. Whenever possible, choose an authentic app or physical security key on SMS.
