Why Use a FIDO2 Security Key Card for Dropbox?
Passwords are easy to forget and even easier to steal. Phishing, brute-force attacks, and data leaks happen every day. FIDO2 security key cards solve these problems by:
- Eliminating passwords: Log in with a tap—no more typing or remembering complex passwords.
- Stopping phishing: Hardware-based authentication means only your key can unlock your account, even if someone tricks you into sharing your info.
- Protecting against hacks: Even if your password leaks, hackers can’t get in without your physical key.
How Does a FIDO2 Security Key Card Work?
FIDO2 keys use public-key cryptography to keep your credentials safe:
- Registration: When you link your Cryptnox key to Dropbox, a unique key pair is created. The public key is stored with Dropbox; the private key stays locked on your card.
- Login: When you log in, Dropbox sends a challenge. You tap your card, which signs the challenge with your private key.
- Verification: Dropbox checks the signed response with your public key. Only your card can create the right signature, so only you get in.
