Create Sync Passphrase for Chrome Extensions

Google Sync Passphrase is a security feature in Google Chrome that allows you to encrypt your data with advanced encryption. Sync Passphrase adds an additional layer of security by encrypting your Chrome data and storing it in the cloud without letting Google read it.

In case, you forget the sync passphrase or want to turn off the passphrase, you can reset the Chrome Sync which will remove the passphrase.

If you have already set up a sync passphrase on another device, you will see the ‘Data was encrypted with your sync passphrase on ….’. in the Sync settings of Chrome. This means you will need to enter the passphrase whenever you sign in to a new browser.
