Secure mobile payment transactions enabled by Android Protected Confirmation

Posted by Rae Wang, Director of Product Management (Android Security and Privacy Team)

Unlike other mobile OSes, Android is built with a transparent, open-source architecture. We firmly believe that our users and the mobile ecosystem at-large should be able to verify Android’s security and safety and not just take our word for it.

We’ve demonstrated our deep belief in security transparency by investing in features that enable users to confirm that what they expect is happening on their device is actually happening.

The Assurance of Android Protected Confirmation

One of those features is Android Protected Confirmation, an API that enables developers to utilize Android hardware to provide users even more assurance that a critical action has been executed securely. Using a hardware-protected user interface, Android Protected Confirmation can help developers verify a user’s action intent with a very high degree of confidence. This can be especially useful in a number of user moments – like during mobile payment transactions – that greatly benefit from additional verification and security.

We’re excited to see that Android Protected Confirmation is now gaining ecosystem attention as an industry-leading method for confirming critical user actions via hardware. Recently, UBS Group AG and the Bern University of Applied Sciences, co-financed by Innosuisse and UBS Next, announced they’re working with Google on a pilot project to establish Protected Confirmation as a common application programmable interface standard. In a pilot planned for 2023, UBS online banking customers with Pixel 6 or 7 devices can use Android Protected Confirmation backed by StrongBox, a certified hardware vault with physical attack protections, to confirm payments and verify online purchases through a hardware-based confirmation in their UBS Access App.


Demonstrating Real-World Use for Android Protection Confirmation

We’ve been working closely with UBS to bring this pilot to life and ensure they’re able to test it on Google Pixel devices. Demonstrating real-world use cases that are enabled by Android Protected Confirmation unlocks the promise of this technology by delivering improved and innovative experiences for our users. We’re seeing interest in Android Protected Confirmation across the industry and OEMs are increasingly looking at how to build even more hardware-based confirmation into critical security user moments. We look forward to forming an industry alliance that will work together to strengthen mobile security and home in on protecting confirmation support.

How we fought bad apps and bad actors in 2022

Posted by Anu Yamunan and Khawaja Shams (Android Security and Privacy Team), and Mohet Saxena (Compute Trust and Safety)

Keeping Google Play safe for users and developers remains a top priority for Google. Google Play Protect continues to scan billions of installed apps each day across billions of Android devices to keep users safe from threats like malware and unwanted software.

In 2022, we prevented 1.43 million policy-violating apps from being published on Google Play in part due to new and improved security features and policy enhancements — in combination with our continuous investments in machine learning systems and app review processes. We also continued to combat malicious developers and fraud rings, banning 173K bad accounts, and preventing over $2 billion in fraudulent and abusive transactions. We’ve raised the bar for new developers to join the Play ecosystem with phone, email, and other identity verification methods, which contributed to a reduction in accounts used to publish violative apps. We continued to partner with SDK providers to limit sensitive data access and sharing, enhancing the privacy posture for over one million apps on Google Play.

With strengthened Android platform protections and policies, and developer outreach and education, we prevented about 500K submitted apps from unnecessarily accessing sensitive permissions over the past 3 years.

Developer Support and Collaboration to Help Keep Apps Safe

As the Android ecosystem expands, it’s critical for us to work closely with the developer community to ensure they have the tools, knowledge, and support to build secure and trustworthy apps that respect user data security and privacy.

In 2022, the App Security Improvements program helped developers fix ~500K security weaknesses affecting ~300K apps with a combined install base of approximately 250B installs. We also launched the Google Play SDK Index to help developers evaluate an SDK’s reliability and safety and make informed decisions about whether an SDK is right for their business and their users. We will keep working closely with SDK providers to improve app and SDK safety, limit how user data is shared, and improve lines of communication with app developers.


We also recently launched new features and resources to give developers a better policy experience. We’ve expanded our Helpline pilot to give more developers direct policy phone support. And we piloted the Google Play Developer Community so more developers can discuss policy questions and exchange best practices on how to build safe apps.

More Stringent App Requirements and Guidelines

In addition to the Google Play features and policies that are central to providing a safe experience for users, each Android OS update brings privacy, security, and user experience improvements. To ensure users realize the full benefits of these advances — and to maintain the trusted experience people expect on Google Play — we collaborate with developers to ensure their apps work seamlessly on newer Android versions. With the new Target API Level policy, we’re strengthening user security and privacy by protecting users from installing apps that may not have the full set of privacy and security features offered by the latest versions of Android.

This past year, we rolled out new license requirements for personal loan apps in key geographies – Kenya, Nigeria, and Philippines – with more stringent requirements for loan facilitator apps in India to combat fraud. We also clarified that our impersonation policy prohibits the impersonation of an entity or organization – helping to give users more peace of mind that they are downloading the app they’re looking for.

We are also working to help fight fraudulent and malicious ads on Google Play. With an updated ads policy for developers, we are providing key guidelines that will improve the in-app user experience and prohibit unexpected full screen interstitial ads. This update is inspired by the Mobile Apps Experiences – Better Ads Standards.

Improving Data Transparency, Security Controls and Tools

We launched the Data safety section in Google Play last year to give users more clarity on how their app data is being collected, shared, and protected. We’re excited to work with developers on enhancing the Data safety section to share their data collection, sharing, and safety practices with their users.

In 2022, the Google Play Store was the first commercial app store to recognize and display a badge for any app that has completed an independent security review through App Defense Alliance’s Mobile App Security Assessment (MASA). The badge is displayed within an app’s respective Data Safety section. MASA leverages OWASP’s Mobile Application Security Verification Standard, which is the most widely adopted set of security requirements for mobile applications. We’re seeing strong developer interest in MASA with widely used apps across major app categories, e.g., Roblox, Uber, PayPal, Threema, YouTube, and many more.

This past year, we also expanded the App Defense Alliance, an alliance of partners with a mission to protect Android users from bad apps through shared intelligence and coordinated detection. McAfee and Trend Micro joined Google, ESET, Lookout, and Zimperium, to reduce the risk of app-based malware and better protect Android users.

We’ve also continued to enhance protections for developers and their apps, such as hardening Play Integrity API with KeyMint and Remote Key Provisioning.

Bringing Continuous Security and Privacy Enhancements to Pixel Users

For Pixel users, we added more powerful features to help keep our users safe. The new security and privacy settings have been launched to all Pixel devices running Android 13, improving the security and privacy posture for millions of users’ around the world every month. Private Compute Core also allows Pixel phones to detect harmful apps in a privacy preserving way.

Looking Ahead

We remain committed to keeping Google Play and our ecosystem of users and developers safe, and we look forward to many exciting security and safety announcements in 2023.

Celebrating SLSA v1.0: securing the software supply chain for everyone

Bob Callaway, Staff Security Engineer, Google Open Source Security team

Last week the Open Source Security Foundation (OpenSSF) announced the release of SLSA v1.0, a framework that helps secure the software supply chain. Ten years of using an internal version of SLSA at Google has shown that it’s crucial to warding off tampering and keeping software secure. It’s especially gratifying to see SLSA reaching v1.0 as an open source project—contributors have come together to produce solutions that will benefit everyone.

SLSA for safer supply chains

Developers and organizations that adopt SLSA will be protecting themselves against a variety of supply chain attacks, which have continued rising since Google first donated SLSA to OpenSSF in 2021. In that time, the industry has also seen a U.S. Executive Order on Cybersecurity and the associated NIST Secure Software Development Framework (SSDF) to guide national standards for software used by the U.S. government, as well as the Network and Information Security (NIS2) Directive in the European Union. SLSA offers not only an onramp to meeting these standards, but also a way to prepare for a climate of increased scrutiny on software development practices.

As organizations benefit from using SLSA, it’s also up to them to shoulder part of the burden of spreading these benefits to open source projects. Many maintainers of the critical open source projects that underpin the internet are volunteers; they cannot be expected to do all the work when so many of the rewards of adopting SLSA roll out across the supply chain to benefit everyone.

Supply chain security for all

That’s why beyond contributing to SLSA, we’ve also been laying the foundation to integrate supply chain solutions directly into the ecosystems and platforms used to create open source projects. We’re also directly supporting open source maintainers, who often cite lack of time or resources as limiting factors when making security improvements to their projects.

Our Open Source Security Upstream Team consists of developers who spend 100% of their time contributing to critical open source projects to make security improvements. For open source developers who choose to adopt SLSA on their own, we’ve funded the Secure Open Source Rewards Program, which pays developers directly for these types of security improvements.

Currently, open source developers who want to secure their builds can use the free SLSA L3 GitHub Builder, which requires only a one-time adjustment to the traditional build process implemented through GitHub actions. There’s also the SLSA Verifier tool for software consumers. Users of npm—or Node Package Manager, the world’s largest software repository—can take advantage of their recently released beta SLSA integration, which streamlines the process of creating and verifying SLSA provenance through the npm command line interface. We’re also supporting the integration of Sigstore into many major package ecosystems, meaning that users can sign and verify artifacts directly from package management tooling, without having to manage keys. Our intention is to continue to expand these types of integrations across open source ecosystems so supply chain security solutions are universal and easily accessible.

We’re also making it easier for everyone to understand their dependencies. Vulnerabilities like Log4Shell have shown the importance (and difficulty) of knowing what projects you depend on and where their security weaknesses might be. Developers can use the deps.dev API to generate real dependency graphs, with OpenSSF Scorecard security scores and other security metadata for each dependency they use. They can also use OSV-Scanner to generate a high quality list of actionable vulnerabilities in those dependencies. In the future, we hope to support automatic remediation and patching through the OSV database service, minimizing the effort that open source developers spend on securing their projects.

Continued community contributions

Ultimately, our goal is to make supply chain security invisible and available to everyone, built directly into each ecosystem for frictionless adoption. To get there, we’ll continue contributing to these efforts and encouraging other organizations who rely on open source to similarly dedicate developers to upstream support. The internet as we know it today wouldn’t be available without open source software, and it’s in everyone’s best interests to give back to the communities that make modern software development possible.

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.
