# Password protect a board file

> Encrypt a .board file with a password so only people who know it can open the board. The password is never sent to the cloud.

Password protection encrypts a board file, so the board can only be opened with the password. Use it for boards that hold sensitive plans or client material, especially when the file is shared by email or kept on a shared drive.

## Encrypt a board file

2. Choose **Encrypt .board file** (1).

1. In the **Password protect file** dialog, type a strong password in **Enter password key** (1) and type it again in **Re-enter password key**.
2. Click **Protect** (2).

From now on, MockFlow asks for the password every time the file is opened.

## Keep the password safe

The file is encrypted with an AES 256 bit cipher, and the password is not stored in the cloud or anywhere else by MockFlow. If the password is lost, the board cannot be recovered. Keep it in a password manager.

## Change or remove the password

Open the protected file, then open the board menu:

- **Change encryption key** sets a new password.
- **Remove encryption key** removes the protection, so the file opens without a password.
