To set, change, or remove the password on a ShareRoom, open the Share tab in the SpiderOak One or Groups application running on your computer. Select the ShareRoom you want to modify, then press Edit. In the Optional Password field, enter the new password you wish to set. If you are removing an existing password, delete the contents of this field, leaving it blank. Then press Save.
Because of the encryption involved, changing a password is not instantaneous. First, the backup application on your computer must encrypt it. The application will indicate that it is working during this time. Then the encrypted data has to be uploaded to your account's server, and from there propagate. When you change a password, our advice is to let the application finish its work and uploading, then wait another minute before testing the new password.
