Two-factor authentication is an extra layer of security used to ensure that people trying to gain access to an online account are who they say they are. It typically requires two different types of verification, such as a code sent via SMS message or a biometric scan, in order to trigger authentication. This additional step makes it difficult for hackers to gain access and decreases the likelihood of unauthorized access.

Steps to enhance account security

1. Enable two-factor authentication wherever available.
2. Make sure to use strong, unique passwords for each account.
3. Enable login notifications for all accounts, so you can see when there are attempts to access your account.
4. Update your passwords regularly.
5. Ensure all devices used to log in to accounts have up-to-date operating system and software security updates.
