About This Skill
What it does
This skill provides best practices for implementing two-factor authentication (2FA) to enhance account security. It covers methods like time-based one-time passwords (TOTP), hardware tokens, and backup codes, ensuring users can secure their systems effectively.
When to use it
- Setting up 2FA for user accounts on web applications or services
- Auditing existing authentication workflows for vulnerabilities
- Educating teams on secure 2FA implementation strategies
Key capabilities
- Recommends TOTP as a standard method for generating one-time codes
- Explains the importance of hardware tokens for high-security environments
- Highlights the need for backup codes to prevent lockouts due to lost devices
- Advises against using SMS-based 2FA due to potential interception risks
Example prompts
- "How should I implement TOTP in my web application?"
- "What are the best practices for issuing backup codes during 2FA setup?"
- "Why is hardware token authentication more secure than app-based 2FA?"
Tips & gotchas
- Ensure users have access to a secondary authentication method, such as backup codes or a physical token.
- Avoid relying solely on SMS-based 2FA due to vulnerabilities like SIM swapping.
