Email

International internet platforms usually require users to register an account with an email address (a few platforms also support registration with a phone number). Email is your unique identity verification method on a platform, so choosing a stable and reliable email is very important.

We recommend using a Gmail account (click to buy) or an Outlook account (click to buy).

You can also choose an email from another international platform, but make sure it is stable and able to receive emails from other platforms.

Bound email

The services of international internet platforms must be registered with an email address, and the email used at registration is the “bound email”.

The bound email usually cannot be changed. When a user logs in or uses platform services, the platform verifies the user's identity by sending an email containing a “verification code” or “verification link” to the bound email.

The user can log in or use platform services with the verification code received or by clicking the verification link.

Recovery email

A recovery email is an email associated with the primary email. Some platforms (such as Gmail or Outlook) require users to provide another email as a recovery email during registration to further confirm the uniqueness of the user's identity.

The recovery email can be an email from the same platform or from another platform. When logging in or verifying identity, the platform may send an email containing a “verification code” or “verification link” to the recovery email, and the user must complete identity verification using this information.

2FA

2FA, also known as two-factor authentication (or two-step verification), is a security mechanism that confirms identity by requiring users to provide two verification methods (such as a password and a verification code received on a phone) when logging in, significantly improving account security. Common methods include SMS verification codes, dynamic codes generated by an authenticator app, or verification links received at the bound email.

We recommend enabling 2FA for important accounts and ensuring that the bound email or recovery email is secure and reliable.

The 2FA code provided by this site is a string combining numbers and letters, and you can use the 2FA code verification-code generator platform (click to go directly) to compute the verification code it is bound to.
