## How can I add stronger security for my Google Account?

We recommend [Google 2-Step Verification](https://www.google.com/landing/2step/)
to protect the Google Account associated with your corporate email. Each time
you sign in to your Google Account, you'll need your password and a verification
code. [Get

If your organization needs more control over your employees' Google Accounts
that are used for work, consider [Google Cloud
Identity](https://cloud.google.com/identity/#features).

## Which versions of TLS do the zero-touch enrollment APIs support?

The zero-touch enrollment APIs support TLS 1.0, TLS 1.1, and TLS 1.2.

You can prevent TLS downgrade attacks by disabling older versions of TLS in your
app's network configuration.

## Which Android device form factors are supported for zero-touch enrollment?

Google provides full support for Android phone and tablet form factors. Support
for Android devices with other form factors is provided on a reasonable-effort
basis only, as setup wizard customizations by device manufacturers may affect
zero-touch enrollment compatibility.
