We don't use security keys for secondary authentication in 2-factor authentication (2FA). Dashlane is the first major password manager to offer FIDO2 security keys as the primary way to access your vault, delivering phishing-proof security in a single step.
Create a passwordless account protected by a security key
When you use a passwordless account protected by a security key, you get the protection of two factors in one:
- Something you have—the physical security key
- Something you know—the PIN used to unlock the key
This combination delivers strong, phishing-resistant authentication in a single step. Instead of requiring a second factor, your security key replaces the password entirely while still ensuring multiple layers of protection.
You can also use a security key to unlock the Dashlane in your web browser, an alternative to entering your Master Password called Biometric unlock.
