What are some alternatives to 2FA authenticator apps?
There are several alternatives to traditional 2FA authenticator apps, such as SMS-based codes, email verification, and hardware tokens.
Can you explain how SMS-based codes work?
Sure! With SMS-based 2FA, a code is sent to your mobile phone via text message, which you then enter to verify your identity.
Are there any security concerns with using SMS for 2FA?
Yes, SMS can be vulnerable to interception and SIM swapping attacks, so it's generally considered less secure than other methods.
What about using hardware tokens? How do they compare?
Hardware tokens generate codes on a physical device, providing a higher level of security since they are not susceptible to online attacks.
