Google Authenticator now supports Google Account synchronization
Christiaan Brand, Group Product Manager
We are excited to announce an update to Google Authenticator, across both iOS and Android, which adds the ability to safely backup your one-time codes (also known as one-time passwords or OTPs) to your Google Account.
Across all of your online accounts, signing in is the front door to your personal information. It’s also the primary entry point for risks, making it important to protect.
We make signing into Google, and all the apps and services you love, simple and secure with built-in authentication tools like Google Password Manager and Sign in with Google, as well as automatic protections like alerts when your Google Account is being accessed from a new device.
We released Google Authenticator in 2010 as a free and easy way for sites to add “something you have” two-factor authentication (2FA) that bolsters user security when signing in. While we’re pushing towards a passwordless future, authentication codes remain an important part of internet security today, so we’ve continued to make optimizations to the Google Authenticator app.
One major piece of feedback we’ve heard from users over the years was the complexity in dealing with lost or stolen devices that had Google Authenticator installed. Since one time codes in Authenticator were only stored on a single device, a loss of that device meant that users lost their ability to sign in to any service on which they’d set up 2FA using Authenticator.
With this update we’re rolling out a solution to this problem, making one time codes more durable by storing them safely in users’ Google Account. This change means users are better protected from lockout and that services can rely on users retaining access, increasing both convenience and security.
In addition to one-time codes from Authenticator, Google has long been driving multiple options for secure authentication across the web. Google Password Manager securely saves your passwords and helps you sign in faster with Android and Chrome, while Sign in with Google allows users to sign in to a site or app using their Google Account. We’ve also been working with our industry partners and the FIDO Alliance to bring even more convenient and secure authentication offerings to users in the form of passkeys.
To try the new Authenticator with Google Account synchronization, simply update the app and follow the prompts.
Making technology for everyone means protecting everyone who uses it. We’re excited to continue building and sharing convenient and secure offerings for users and developers across the web.

Securely Hosting User Data in Modern Web Applications
Posted by David Dworken, Information Security Engineer, Google Security Team
Many web applications need to display user-controlled content. This can be as simple as serving user-uploaded images (e.g. profile photos), or as complex as rendering user-controlled HTML (e.g. a web development tutorial). This has always been difficult to do securely, so we’ve worked to find easy, but secure solutions that can be applied to most types of web applications.
Classical Solutions for Isolating Untrusted Content
The classic solution for securely serving user-controlled content is to use what are known as “sandbox domains”. The basic idea is that if your application’s main domain is
example.com
, you could serve all untrusted content onexampleusercontent.com
. Since these two domains are cross-site, any malicious content onexampleusercontent.com
can’t impactexample.com
.This approach can be used to safely serve all kinds of untrusted content including images, downloads, and HTML. While it may not seem like it is necessary to use this for images or downloads, doing so helps avoid risks from content sniffing, especially in legacy browsers.
Sandbox domains are widely used across the industry and have worked well for a long time. But, they have two major downsides:
It is also worth noting that sandbox domains help mitigate phishing risks since resources are clearly segmented onto an isolated domain.
Modern Solutions for Serving User Content
Over time the web has evolved, and there are now easier, more secure ways to serve untrusted content. There are many different approaches here, so we will outline two solutions that are currently in wide use at Google.
Approach 1: Serving Inactive User Content
If a site only needs to serve inactive user content (i.e. content that is not HTML/JS, for example images and downloads), this can now be safely done without an isolated sandbox domain. There are two key steps:
Content-Type
header to a well-known MIME type that is supported by all browsers and guaranteed not to contain active content (when in doubt,application/octet-stream
is a safe choice).Response Header
Purpose
X-Content-Type-Options: nosniff
Prevents content sniffing
Content-Disposition: attachment; filename="download"
Triggers a download rather than rendering
Content-Security-Policy: sandbox
Sandboxes the content as if it was served on a separate domain
Content-Security-Policy: default-src ‘none’
Disables JS execution (and inclusion of any subresources)
Cross-Origin-Resource-Policy: same-site
Prevents the page from being included cross-site
This combination of headers ensures that the response can only be loaded as a subresource by your application, or downloaded as a file by the user. Furthermore, the headers provide multiple layers of protection against browser bugs through the CSP sandbox header and the
default-src
restriction. Overall, the setup outlined above provides a high degree of confidence that responses served in this way cannot lead to injection or isolation vulnerabilities.Defense In Depth
While the above solution represents a generally sufficient defense against XSS, there are a number of additional hardening measures that you can apply to provide additional layers of security:
X-Content-Security-Policy: sandbox
header for compatibility with IE11Content-Security-Policy: frame-ancestors 'none'
header to block the endpoint from being embeddedproduct.usercontent.google.com
)Cross-Origin-Opener-Policy: same-origin
andCross-Origin-Embedder-Policy: require-corp
to enable cross-origin isolationApproach 2: Serving Active User Content
Safely serving active content (e.g. HTML or SVG images) can also be done without the weaknesses of the classic sandbox domain approach.
The simplest option is to take advantage of the
Content-Security-Policy: sandbox
header to tell the browser to isolate the response. While not all web browsers currently implement process isolation for sandbox documents, ongoing refinements to browser process models are likely to improve the separation of sandboxed content from embedding applications. If SpectreJS and renderer compromise attacks are outside of your threat model, then using CSP sandbox is likely a sufficient solution.At Google, we’ve developed a solution that can fully isolate untrusted active content by modernizing the concept of sandbox domains. The core idea is to:
exampleusercontent.com
to the PSL, you can ensure thatfoo.exampleusercontent.com
andbar.exampleusercontent.com
are cross-site and thus fully isolated from each other.*.exampleusercontent.com/shim
are all routed to a static shim file. This shim file contains a short HTML/JS snippet that listens to themessage
event handler and renders any content it receives.$RANDOM_VALUE.exampleusercontent.com/shim
and usespostMessage
to send the untrusted content to the shim for rendering.Compared to the classic sandbox domain approach, this ensures that all content is fully isolated on a unique site. And, by having the main application deal with retrieving the data to be rendered, it is no longer necessary to use capability URLs.
Conclusion
Together, these two solutions make it possible to migrate off of classic sandbox domains like
googleusercontent.com
to more secure solutions that are compatible with third-party cookie blocking. At Google, we’ve already migrated many products to use these solutions and have more migrations planned for the next year. We hope that by sharing these solutions, we can help other websites easily serve untrusted content in a secure manner.Discarded, not destroyed: Old routers reveal corporate secrets
