Acronis Sercure Zone Password Protection

Hi,

I'm interested to know how secure is the Acronis Secure Zone password.

We can select a password when creating an Acronis Secure Zone but unlike the individual backups themself where we can select the level of encryption, we don't get any info as to how secure is the password we select for the Acronis Secure Zone creation.

in other words, how easy of difficult is it to crack the password for the Acronis Secure Zone itself and get access to all the backups inside ?

thank you in advance
