What are the common types of MFA solutions?

There are several common types of MFA solutions that businesses may adopt, including:

  1. Hardware tokens: Physical devices that generate a unique, one-time-use code for authentication.
  2. Software tokens: Apps or programs on a user’s mobile device or computer that generate a unique code or prompt for additional authentication factors.
  3. Biometrics: Verification methods such as fingerprint scanning, facial recognition, or voice recognition.
  4. SMS-based tokens: Unique codes sent to a user’s mobile device via text message.

Each type of MFA solution has its advantages and drawbacks, and businesses should consider their specific security needs and user accessibility requirements when selecting an MFA solution.
