Adding devices

After creating your account, you may want to install Seald on another device.

There are three methods to pair a device with a Seald account using the desktop application:

• in GUI with the mobile application;
• command line interface;
• with the administrator recovery key (only available through a support request from Seald).

DANGER

If you force the re-creation of a user account with the same email address on a new computer, the account on the old computer will become inoperative, and the account on the new device will not have access to protected documents & emails from and to the old device.

From the graphical interface

To add a device from the GUI, use the Seald mobile application as an intermediary (available on the stores) :

1. On the smartphone, install the Seald mobile application;
2. On the computer correctly configured on the Seald account, click on the gear wheel, then click on "Add new device";
3. From the Seald mobile application, click on "Pair device";
4. Scan the QRCode;
5. Check that the codes match, and validate.

A re-encryption operation will be triggered to re-encrypt all old encrypted files & emails for the new device.

1. On the mobile application newly paired with the account, go to the menu on the left, then to "Add a new device" ;
2. On a new computer with Seald installed, select "I already have an account" ;
3. Scan the QRCode displayed with the mobile application ;
4. Check that the codes match, and validate.

A re-encryption operation will be triggered to re-encrypt all old encrypted files & emails for the new device.

On the command line

It is possible to use the command line interface to create keys for a new device. Keys that will have to be transmitted from one machine to another.

To do this, you need :

1. Exit the desktop application (it is not possible to use the CLI with the launched application) ;
2. Execute the following creation command :

cd %LOCALAPPDATA%\Programs\Seald
seald-cli create-backup-key --device-name "new device" --output ./my-key

1. Choose a strong password for the new device key

A file named my-key has been created, and it is protected by the chosen password. It must be transferred to the new device, and loaded into Seald.

To do this, you need to :

1. Make sure that Seald is installed, exited and does not have an account created on this device ;
2. Execute the following creation command :

cd %LOCALAPPDATA%\Programs\Seald
seald-cli load-backup-key --key ./my-cle

1. Enter the password for the key and press the enter key.
