A strong password provides essential account protection, but passwords can still be stolen through phishing, malware, data breaches, or unsafe devices. Two-factor authentication adds another security layer that can prevent unauthorised access.
How Two-Factor Authentication Works
After entering your password, the platform asks you to complete a second verification step. This may involve entering a temporary code, approving a login notification, scanning a fingerprint, or using a physical security key.
An attacker who knows your password may still be unable to enter the account without the additional verification method.
Choose a Secure Verification Method
Text-message codes are widely used and provide more protection than relying on a password alone. However, authentication applications are usually safer because the codes are generated directly on your device.
Physical security keys offer strong protection for sensitive accounts. Biometric verification, such as fingerprints or facial recognition, may also be available on compatible devices.
Use the strongest method supported by the platform.
Store Your Backup Codes Safely
When enabling two-factor authentication, many services provide recovery or backup codes. These codes allow you to sign in if your phone is lost, damaged, or unavailable.
Save them in a secure password manager, locked document, or safe physical location. Do not store them in an unprotected screenshot or share them with anyone.
Review Trusted Devices
Some platforms allow you to skip repeated verification on trusted devices. Only select this option on your personal phone or computer.
Never trust a public, workplace, hotel, library, or shared device. Remove old devices from your security settings when you no longer use them.
Protect Your Email Account First
Your email account is often used to reset passwords for other services. Enable two-factor authentication on your email before securing less important accounts.
Prioritise financial, shopping, cloud storage, social media, and business accounts.
