If your institution uses external authentication, you do not need a local VoiceThread password. Your VoiceThread access is based on your membership in that external system.
Local VoiceThread passwords must be at least 6 alphanumeric characters.
VoiceThread encrypts passwords using the peer-reviewed, industry-standard bcrypt password hashing function with a suitable work factor that balances attacker and defender verification. VoiceThread imposes no practical limit on overall password length or usable character set. VoiceThread generates salts using a cryptographically-secure source.
