Ledger Sync: Effortlessly Sync Your Accounts in Ledger Live — Safely, Securely, and with Complete Privacy

There’s a good chance that you already use a few online applications with account synchronization. Whether it’s for listening to your favorite music streamer, logging onto social media, or answering your emails, the experience of using all our favorite applications on all our different devices is one we’ve come to take for granted. 

While the data sharing that makes this account synchronization possible is commonplace in Web2 applications, implementing a similar solution for decentralized apps while maintaining the same privacy is more challenging. 

This is also true for Ledger Live, meaning synchronization of your data on both your phone and laptop was previously inconvenient. 

But we solved the problem!

Thanks to Ledger Sync, a feature that relies on Ledger Key Ring Protocol, Ledger Live users can enjoy a seamless experience, with easy access to all their Ledger Live data across multiple devices. 

With Ledger Sync you can effortlessly sync your accounts in Ledger Live—safely, securely, and with complete privacy.

Let’s see how it works.

What is Ledger Sync? 

Ledger Sync is an optional service that provides a simple and secure way for Ledger Live users to sync instances of Ledger Live across multiple devices. In other words, you can now activate the feature to synchronize the Ledger Live application on your desktop and the Ledger Live app on your mobile device every 10 seconds. This allows for a more user-friendly experience, perfect for those who use Ledger Live on multiple devices such as a smartphone and laptop.

Besides that, Ledger Sync also lets you backup account data. In fact, it’s the world’s first secure and private backup solution that doesn’t require an email and password! This offers peace of mind if your laptop or smartphone gets lost or damaged. Simply set up your Ledger Live on your new device and connect your wallet to access your Ledger Live data immediately.

How Ledger Sync Works

Maintaining privacy on decentralized networks is an inherent challenge. This is particularly apparent in the case of data sharing, which is necessary for a service like Ledger Sync to operate.

To combat this challenge, Ledger Sync uses the Ledger Key Ring Protocol to generate encryption keys from the security of your device, and it’s these keys that encrypt your Ledger Live data. Once the data is encrypted, it’s safe to be sent via public channels. Absolutely no one except the owner of the hardware wallet can encrypt that information — not even Ledger! 

The only way to restore the encryption keys—and the data they encrypt—is via a device set up with the same secret recovery phrase as the one you initiated the Sync from. 

Ledger Key Ring Protocol: How it enables Ledger Sync

Ledger Key Ring protocol enables multiple applications or multiple instances of the same application to access shared information, using your Ledger hardware wallet as a central point for end-to-end encryption. It’s a protocol Ledger developed for use in multiple applications far beyond the Ledger Ecosystem. To learn more about Ledger Key Ring Protocol, make sure you read Ledger CTO Charles Guillemet’s blog post and the Ledger Key Ring Protocol whitepaper.

However, in the case of Ledger Sync, the Ledger Key Ring Protocol enables multiple instances of the same application: Ledger Live. Essentially, it allows separate instances of Ledger Live (for example, Ledger Live on your desktop and Ledger Live on your mobile device) to share data without revealing it to other parties—even when it’s shared over public networks. This means your Ledger Live data stays private and within your control.

Ledger Sync: An Improved User Experience for Ledger Live

Ledger Key Ring Protocol is a major development that promises increased functionality and ease of use, not just for Ledger users, but for Web3 users as a whole. And Ledger Sync is just the first service to benefit from that.

Thanks to Ledger Sync, Ledger Live is more convenient than ever. No matter which device you use, either your smartphone or laptop, your Ledger Live will show the same information, making it secure, efficient, and easy to use — without compromising your privacy.
