Google Authenticator. What data is transmitted to the site?

Question

Information Security

Hello!

Can you please tell me what data is transmitted when using Google Authenticator?

I need to set up two-factor authentication on Linkedin on 40 accounts. If I use one of my Google Authenticator apps, can LinkedIn link these accounts together? What information will LinkedIn receive?

Answer 1

Google Authenticator does not transmit anything, it only generates a pin code according to the secret.
