How many types of two factor authentication exist
There are several different types of 2FA, each with its own pros and cons. The most common are:
- - Flash call-based: A code is sent to your mobile phone via a phone call, which you then use to log in.
- - SMS-based: A code is sent to your mobile phone via text message, which you then use to log in.
- - App-based: A code is generated by a security app on your phone, which you then use to log in.
- - Biometric: Your fingerprint or other biometric data is used to verify your identity.
Which type of 2FA is right for you depends on your needs and preferences. SMS-based 2FA is the most convenient, but it’s also the least secure since text messages can be intercepted. App-based 2FA is more secure, but it requires you to have your phone with you at all times. Biometric 2FA is the most secure option, but it’s also the most expensive and not all devices support it.
Flashcall is one type of two factor authentication that is growing in popularity due to its ease of use. With flashcall, you simply enter your phone number when prompted and you will receive an automatic call with a verification code.
