The TOTP spec (RFC 6238) recommends encrypting the keys. http://tools.ietf.org/html/rfc6238 How: Borrow the encryption code from the `attr_encrypted` gem and use it to encrypt and decrypt the `otp_secret_key` attribute. Allow users to add encryption by passing in `encrypted: true` to `has_one_time_password`. This provides backwards-compatibility for existing users of the gem.
