Password policy

Crunch has a simple policy for acceptable passwords:

• It must be 8 characters or longer
• It must contain at least 4 unique characters

Examples:

• Secure 8 character password: 4B3a8f4$
• Secure passphrase: correct horse battery staple

We highly recommend that users use long pass phrases instead of passwords for security and for ease of remembering the credentials for accessing the service.
