Password complexity rules

What are the rules for passwords? Are there any unaccepted characters? Is there a minimal complexity?

At the moment, no complexity rules are enforced for cryoSPARC passwords, and no characters are explicitly prohibited.
CryoSPARC user accounts and passwords help control access to the interface within a trusted private network, but please note that cryoSPARC passwords are not intended as a barrier against malicious access. The network and computer hosting a cryoSPARC instance must be protected from all malicious and unauthorized access by other means, even when using cryoSPARC’s user management.
