2FA or Two-Factor Authentication is an additional layer of security for your account. Users can choose to set it up in order to prevent their account from being stolen. There are two ways to use 2FA:
You can set up 2FA through your phone by receiving a code through an SMS when you try to log in to your account.
You can set up 2FA through an Authenticator app and you will receive a code through this app when you try to log in.
For Android users we recommend using authenticator apps such as 'Authy' or 'Google Authenticator'.
For iOS users we recommend using authenticator apps such as 'Authy' or '1Password'.
You can turn on/off and edit devices, apps you use for 2FA through your account panel.
