When you run SecretFolder, a password entry window appears on the screen as the program starts for user authentication. This window contains a text field where you can enter your password, and you must enter the password you are currently using exactly. After entering the password, click the OK button to launch SecretFolder normally and access your protected files.

To change the password while SecretFolder is running, first find the Preferences button in the program window. Clicking this Preferences button opens the settings menu, where you can adjust various SecretFolder options.

When the Settings menu opens, find and click the "Change Password" button among the available options. This button is usually located under the security-related settings and may be labeled "Change Password" Clicking the Change Password button opens a new window where you can proceed with changing your password.

When the password settings window opens, you will see an input field where you can enter a new password. Carefully enter the new password you want to use here. For security, the password should be sufficiently long and complex, and you may need to enter the same password again for confirmation. Once all entries are complete, click the OK button to finish changing the password. After that, you will be able to access SecretFolder using the newly set password.
