Two-factor authentication (2FA, TFA), also known as step-by-step verification or multi-factor verification, is a means of protecting your account not only by entering a username and password, but also using a code known only to you, as the owner of the account.
After enabling 2FA, entering a six-digit code will be a required step every time you log into your account.

In our case, to pass two-factor authentication, you will need a mobile phone with a special one-time code generator application or an installed Telegram messenger.
2FA is an additional measure to protect your funds - when using it, it is almost impossible for unauthorized persons to enter your account.
