Frequently Asked Questions
What are 2FA backup codes?
2FA (Two-Factor Authentication) backup codes are one-time use recovery codes that let you access your account when you can't use your primary 2FA method (like your phone or authenticator app).
How many backup codes should I generate?
Most services provide 8-10 backup codes. This gives you enough codes for emergencies while not being so many that they become hard to manage.
How should I store backup codes?
Print them and store in a secure location, save them in an encrypted password manager, or keep them in a safety deposit box. Never store them digitally without encryption.
What format should backup codes use?
Alphanumeric codes (8-10 characters) are common and easy to type. Some prefer numeric-only codes which are easier on phone keyboards but need to be longer for security.
Are these backup codes secure?
Yes, these codes are generated using cryptographically secure random number generation in your browser. They are not stored or transmitted anywhere.
