Sync browser data on Android

This post is also available in: 日本語 Русский Français Español Deutsch Nederlands Српски Українська Dansk Português Português Български 简体中文

Sync bookmarks, passwords, open tabs and more between your desktop and mobile devices by logging-in to your Vivaldi Account.

Important! Sync is not meant to be used as a data backup service. If the data is not stored locally on any devices, we can’t guarantee you’ll be able to restore the data on a later date.

Access Sync

To access Sync settings, go to Vivaldi menu > Settings > Sync > Log in / Create Account.

First, log in to your Vivaldi account with your account’s username and login password. Your login password is sent to our servers over a secure connection and a hash of it is stored in our database.

In case you don’t have an account yet, create a new Vivaldi account in the Settings window or on With a Vivaldi account, in addition to Sync, you’ll get access to the ForumVivaldi Social, Webmail, Themes and Blogs.

Encryption password

If it’s your first time using Sync, you need to create the encryption password that is used for encrypting your data. The password needs to be at least 12 characters long and you can use any letters, number and characters in it. We recommend using a password that’s different from your login password. Your encryption password is used locally on your computer for encrypting the data you’re about to send to our servers and to decrypt the received data. Your encryption password is never sent to us or any other third party, which ensures that we cannot decrypt your data. This also means that even if someone should get access to your account’s username and login password, it’s impossible for them to find out the encryption password, unless you yourself have shared it with them.

It can happen that you forget the encryption password. When you have the data stored locally and can still access it, forgetting the password isn’t a big deal. You’ll just need to reset the encryption password and upload all the data again. Should you not have access to your browser data on any devices (for example, you used Sync only on one device and had to reset the OS, losing all your data), restoring it requires to have prepared for this beforehand by saving a backup encryption key in a safe place.

Backup Encryption Key

Backup encryption key is an alternative method to the encryption password for decrypting your Sync data. Like with the encryption password, your backup encryption key is never sent to us or any other third party, which ensures that we cannot decrypt your data. For it to be useful, you need to save the key in a safe location, while you can access your Sync settings with the encryption password.

Save the backup encryption key

  1. Log in to your Vivaldi account in Vivaldi menu > Settings > Sync.
  2. Enter the encryption password.
  3. Near the bottom of the page, look for Backup Encryption Key.
  4. Tap Save and save the key file to your device.

The key is valid until you reset the remote Sync data. We recommend storing the key file in a location that can survive something irreparable to your device, such as an external memory drive or a trusted cloud service.

Use the backup encryption key

  1. Log in to your Vivaldi account in Settings > Sync.
  2. When asked for the encryption password, click Load Encryption Key.
  3. Click Load and find the key file.
  4. Click Open.
  5. Start syncing.

Syncing on Mobile

Once you’ve logged in and entered the encryption password, you can select whether to Sync all data or just some of it.

Types of data that can be synced:

Enabling your preferred options will immediately start sync.

Sync settings page on Android

The first Sync, especially with big profiles, can take some time, so you might need to wait a little for all the synced data to appear on your mobile device.

The data to be synced is encrypted end-to-end

The data you send us is encrypted on your computer using a password that is never sent to us. In addition, the servers on which your encrypted data is stored are well protected from intrusion both physically and from the network.

When syncing, the encrypted data is sent to a central server, from which it can be requested from all other Vivaldi instances only by the same user. When one Vivaldi instance sends new data to the Sync server, a notification is immediately sent to all other Vivaldi instances to let them know that they can download this new information. This means you should see changes reflected within a minute.

Vivaldi stores Sync data on its own servers in Iceland. If you want to know more about how we handle your synced data please visit Sync’s Privacy Page.

Stop syncing

When you choose to stop syncing some types of data, the browser forgets all association between your local data and the data located on the Sync server. All your data remains on the Sync server as it was. When you explicitly log out from Sync, the same happens for all the synced data. Please note that quitting the browser does not log you out from Sync.

Delete synced data

To delete synced data from the servers:

  1. Open Sync Settings;
  2. Make sure you’re logged in;
  3. Click on Delete Remote Sync Data.
  4. In the pop up, click on Delete Data;

You will need to make sure that you have all your data client side before doing this to avoid losing data. Note that the data will be re-uploaded if you choose to run sync again in the future.

If, in addition to clearing the data and logging out of Sync, you’re also thinking of deleting your Vivaldi account, please note that when the account is deleted, you will also lose access to all other Vivaldi Community services such as webmail, forum, and blogs and all the data will be deleted. If you still wish to proceed, follow the instructions on our help page about deleting Vivaldi accounts.

Change or reset your account login password

If you wish to change your login password, log in on, go to your profile (top right corner) and change it there. In case you’ve forgotten your password, send yourself a password reset email. Note that if you have chosen to use the same password for login and encryption, changing your login password will not automatically change your encryption password and you will have to do this separately.

Change or reset your encryption password

In case you’ve forgotten your encryption password and don’t have a backup encryption key to decrypt the data or just want to change the encryption password:

  1. Open Sync Settings;
  2. Log into your Vivaldi account;
  3. Click on Forgot password;
  4. In the pop up, click on Delete Data;
  5. Then Restart Sync again and enter a new password.

Your data will be deleted from Vivaldi’s Sync servers and re-uploaded from the computer you’re using once you enter a new password. In case the synced data isn’t stored locally on any devices (e.g. after a OS reset) and you don’t have a backup encryption key to decrypt the data, the synced data will unfortunately be lost when resetting the encryption password.
