When you log in, Dashlane sends a verification code to the email address used to create the Dashlane account. If you've changed your account's contact email, Dashlane sends the code to that email address.

If you enabled 2-factor authentication (2FA) in Dashlane, your third-party authenticator app, such as Dashlane Authenticator or Authy, provides the 6-digit token. This app is likely installed on your smartphone.
