Complete Guide to Brave Sync

Security Notice:
Brave Sync uses a "Sync Code" based on the BIP39 word list. This code is sensitive and should be treated as securely as a password or recovery phrase. Anyone with your Sync Code can join your Sync chain and access synced data.

How to Use Brave Sync

Open Brave browser on your device.
Go to Settings > Sync.
Create a new Sync chain or join an existing one using your Sync Code.
On another device, repeat the process and enter the Sync Code to join the chain.

How Secure Is Brave Sync?

Your Sync Code is essentially a cryptographic seed; keep it secret.
Brave does not store your Sync Code or synced data.
If someone obtains your Sync Code, they can access your synced bookmarks, history, passwords, etc.
Use device-level security (OS password, biometrics) to protect your Sync Code.

Sync Code Recommendations

Never share your Sync Code with anyone you don’t trust.
Store your Sync Code in a secure password manager.
Do not use screenshots or cloud notes for storage.
If you suspect your Sync Code is compromised, remove devices from the Sync chain and create a new one.

Using the 25th Word

The Brave Sync tool generates a time-based 25th word for Sync Codes.
This word allows for time-limited joining or recovery, and changes daily.
For best security, only use the 25th word as recommended by Brave, and never as your sole backup.
Brave advises using the built-in export features for bookmarks and passwords for robust backup.

Additional Tips

Always use the latest version of Brave for best security.
Enable OS-level encryption where possible.
Be cautious when syncing sensitive data between devices.
