How does 2FA work?

When the 2FA function is activated, the user will be asked to input a short code sent to their device after successfully using their login and password to enter the account. The successful input of the code will confirm the user's identity, and the user will be granted access to the account.

OTP sent to users typically expires after a short period, so the risks of passing the code to another person are lower.
 

The 2FA method is often used when it comes to performing critical actions like conducting financial transfers or making changes to security settings.
