Took a while, but this commenter is finally correct: > Why does Authy require I provide my cell phone number and email address? Why do I have to have a user account? This is completely ridiculous. I do not need nor want cloud syncing or backup. You are making Authy a potential target for attacks by associating a user to cloud stored 2FA information. > This is not in the spirit of 2FA. https://news.ycombinator.com/ite…
The entire use case for Authy is the cloud backup and syncing across devices. If you don’t want that, use any of the other free and more open 2FA apps.
