What does this site do?
Shared2FA is an application that provides you with a virtual phone number. You use the virtual phone number on other websites that require 2-Factor Authentication. Those authentication messages then go through Shared2FA, which will post them to a Slack channel of your choosing.
Is Shared2FA Secure?
TLDR; Yes, Absolutely!
Security is not a simple yes/no question. In some ways Shared2FA could be considered more secure than using a mobile phone because it is not vulnerable to Cell Phone Cloning. In other ways, it could be considered less secure because the message could be delivered to multiple people. You could say it is different.
Within Shared2FA, we use top-notch security in everything, from encrypting all data and communication, to restricting access to servers. Feel free to contact us if you have any specific questions.
