  "title": "ruby-devise-two-factor: Under the default configuration, Devise-Two-Factor versions \u0026gt;= 2.2.0 \u0026amp; \u0026lt; 6.0.0 generate TOTP shared secrets...",
  "description": "Under the default configuration, Devise-Two-Factor versions \u0026gt;= 2.2.0 \u0026amp; \u0026lt; 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.",
