      "value": "Under the default configuration, Devise-Two-Factor versions >= 2.2.0 & < 6.0.0 generate TOTP shared secrets that are 120 bits instead of the 128-bit minimum defined by RFC 4226. Using a shared secret shorter than the minimum to generate a multi-factor authentication code could make it easier for an attacker to guess the shared secret and generate valid TOTP codes."

El uso de un secreto compartido m\u00e1s corto que el m\u00ednimo para generar un c\u00f3digo de autenticaci\u00f3n multifactor podr\u00eda facilitar que un atacante adivine el secreto compartido y genere c\u00f3digos TOTP v\u00e1lidos."
