2FA? is a means of securing your account, and will be required to be setup before you can add any lines. By enabling 2FA, you would assure that only you have access to your account. Even if a bad actor discovers your password, they won’t be able to get into your account with your 2FA verification. In addition, you would receive an email anytime someone has both your UID, and password, but didn’t verify with 2FA. This is designed to allow you to change the password immediately.
Anytime someone logging into a device that hasn’t been logged into for 30 days or more will be required for a 2FA authentication. You would have a primary method, and a backup method. This will be in one of the following options:
Authenticator App
An app installed on to your smartphone will provide you with a 6 digit 2FA code that is valid for 30 seconds. If the code changes, then you must enter the new code before preceding. This method is the second best solution for your needs. Obviously, if you don’t have the device with the 2FA device (device stolen), then you would use your backup method. With an authenticator app, you aren’t waiting for that email, or SMS message to give your code to you. This is usually quicker and more reliable than email or SMS.
Email Verification
This is a good option as long as no one else has access to your email. The system will send a 6 digit code that you would have 10 minutes from requesting a 2FA code to get inside. If you haven’t received the 2FA code in your inbox, check your junk/SPAM folder for false positives. This is the third best solution. The email will be very simple, and just the 6 digit code. The sender will be 2fa@pcs1.ws. If you receive such an email, and you aren’t trying to log into your account, then a bad actor has your credentials, and you should log in to change your password immediately.
Hardware Key
An example of this will be a Yubi-Key which I tried to get it to work for me, but it didn’t The idea is I will be able to use the hardware key plugged into one of my USB-C ports. When I need to authenticate, I just use the fingerprint reader, and I will log in. I will be able to remain authenticated for this device for between 0 and 30 days. 0 days will be something similar to using a library, or an Internet café. However, no one should be using an Internet café. If you have a notebook, you could use your router if you have an add-on, or your phone as a modem, and therefore, and shared phone connection.
SMS Verification
The least secured method, it is better than nothing when you need a backup method. You will be given your 6 digit code, and told to not give it to anyone. If you didn’t request this 2FA, then you should log in to change your password immediately.
