I'm implementing Google 2-Factor Authentication on some servers in my company.
When configuring Google 2FA on client computers, 5 emergency codes are generated to be used if a user forgets his master password or loses access to his soft token application.
I would like to save these emergency codes on some centrallized safe place and I was thinking about placing them in some write-only bucket at Amazon s3.
Has any of you done it before? do you have an better suggestion?
