Two-factor authentication (2FA) is crucial for ensuring your online security, as it provides an extra layer of protection by requiring not only your password but also a second form of verification, making it significantly harder for unauthorized users to access your accounts.
By default, your two-factor authentication will be done through a text message to your phone number. You can change to an authenticator app (for example, Google Authenticator):
Go to "Settings" in your account
Click on "Security"
Choose between "text message" and "authenticator app" by clicking on star icon
If you change your two-factor authentication method, you will need to verify it with the previous method.
