cy: MFA, OTP, SMS, U2F, WTF?! - Multifaktor-Authentifizierung ist sehr gut!
Explore the world of multifactor authentication, debunking common myths and exploring secure methods like U2F, FIDO2, and WebAuthn to keep your users and data safe.
- Authenticators: email, SMS, etc. are not secure as they can be intercepted.
- MFA provides an additional layer of security, but it’s not perfect.
- OTP is a common method for MFA, but it’s vulnerable to phishing attacks.
- U2F is a more secure method of MFA, but it has limited adoption.
- FIDO2 is a new standard for MFA that is more secure than U2F.
- WebAuthn is a FIDO2-based authentication protocol.
- MFA should be implemented with multiple factors, including something you know, something you have, and something you are.
- SMS-based MFA is insecure as it can be intercepted.
- Authenticators should be used instead of SMS-based MFA.
- Authenticators need to be properly implemented to be secure.
- Implementing MFA requires careful planning and consideration.
- MFA should be implemented as part of a larger security strategy.
- It’s hard to get people to use MFA properly.
