Two-factor authentication (2FA) is a very important way to protect your online security. It adds an additional level of protection by requiring not only a password but also a second verification method. This makes it much more difficult for unauthorized users to access your accounts.
By default, two-factor authentication is performed by sending an SMS to your phone number. You can also switch to using an authentication app (e.g., Google Authenticator):
To change your 2FA method:
Go to your account Settings
Click on Security
Under two-factor options, select “SMS” or “Authenticator App” by clicking the star icon next to your preferred method
If you change your two-factor authentication method, you’ll need to verify it using the previously active method.
