3. Enable Two-Factor Authentication (2FA)
Benefits of 2FA
- Added Layer of Security: Two-factor authentication adds an extra layer of protection by requiring a second form of verification, such as a text message code or authentication app.
- Protects Against Unauthorized Access: Even if someone obtains your password, they would still need the second factor to gain access.
