Crypto Pass is a sequence of letters and/or numbers that you create to control the access to your files via pCloud Encryption. A Crypto Pass is similar to a password in usage. In this case, you enter this Crypto Pass in order to encrypt and decrypt your Crypto Folder content. Make sure you use a strong enough pass and never forget it. If, however, you do forget it, pCloud cannot return it to you and your encrypted content will be lost.
