Adopt these recommendations to set up two-factor authentication (2FA) on your online accounts:
- Use Push and Silent Device Approval: These are the most secure 2FA channels since they are attached to a specific device and allow you to decline an authentication request, which can assist in identifying fraud.
- Allow customers to set authentication preferences: Remember user preferences for future logins to improve the user experience and reduce discomfort during the authentication process.
- Implement Retry Buffers: Add retry buffers to verification operations to prevent abuse and anxiety among users.
- Use U2F Hardware Keys: For high-value accounts, U2F hardware keys, such as the Yubico YubiKey or Google Titan, are more credible than other authentication methods.
- Educate Users: Inform users about the need for two-factor authentication and how to use it effectively to avoid breaches that result from weak passwords or a lack of awareness.
- Monitor and Analyze Authentication Logs: Monitor authentication logs periodically for suspicious activity in order to identify and act on any security concerns. Remember that 2FA is an essential tool in today’s online world, and any 2FA approach is preferable to none. Authenticator applications are ideal for 2FA, whereas U2F hardware keys are superior for high-value accounts.
