What is Two-Factor Authentication? 

Andreas never disaapoints.

Andreas,I wanted to say thank you for all your information you put out here for everyone. I've been in crypto for several years but had to explain someone else the basics recently. The first resource I gave that person was your channel and books

I enjoyed your video on topic of two factor autentication

Thank You Andreas !!

Useful information 👍 👌

Thank you very much for all of the fantastic content that you provide Andreas! I have recently enrolled for the introduction to digital currency course and thoroughly enjoyed your input. I will also be registering for the MSc starting 31 January 2022. Do you perhaps have any content on how to setup and run my bitcoin lightning node using rasberry pi 400 or any information about the Tron network? Enjoy your day

Thanks Andreas great vedio!

Interesting information, I see it similar.

Most of the times people use SMS for 2FA as i understand there is as way to trick you with that and get access if they know your password

This guy has my full attn. as indicated. Hint drop of the eternity alert..

If that USB you tap also checks your fingerprint. That would be cool.
