You should enable Two Factor Authentication for accessing your account. Note this is optional and it applies for each user, not at account level.
Step 1. Go to My Profile and click the toggle option
Step 2. Open your Two Factor Authentication App and scan the QR Code
You can use any app, like Google Authenticator, Authy, Microsoft Authenticator, Lastpass Authenticator or others you already have.
Enter the token you get in your app to enable the Two Factor Authentication option.
Step 3. You’re done enabling it
You will be asked to enter such a token after you input your email and password every-time you log in.
To disable it, click the toggle again, enter the token and click disable.
