Upgrade devise-two-factor to version 6.0.0 or higher.
Overview
Affected versions of this package are vulnerable to Insufficient Entropy due to the use of an insufficient default, OTP shared secret length.
Workaround
If upgrading to the fixed version is not possible, users are advised to override the default otp_secret_length attribute in the model when configuring two_factor_authenticable and set it to a value of at least 26 to ensure newly generated shared secrets are at least 128-bits long.
