I enabled two factor on my Linode account recently and saw this worrying copy:
> If you lose your token and get locked out of the Linode Manager, email support@linode.com to regain access to your account.
> Should you need us to disable your Two-Factor Authentication, the following information is required:
> An image of the front and back of the payment card on file, which clearly shows both the last 6 digits and owner of the card.
> An image of the front and back of the matching government-issued photo ID.
There doesn't seem to be a way to say "I have my big boy pants on, don't let anyone in under any circumstances". This is the first 2FA setup I've seen that still allows bypass by contacting support.
EDIT: I also find it odd that you have to manually generate a scratch code, and they don't automatically generate it for you. Again, all of the other 2FA setups I've gone through have done this.
