How we can Specify password restrictions?

Teamcenter enables companies to specify restrictions for passwords when creating user accounts.
These password restrictions are controlled through preference settings and take effect upon password creation. Existing passwords are not affected.

Companies can set the following restrictions:

• Minimum length required (PASSWORD_minimum_characters)
• Mixed case required (PASSWORD_mixed_case_required)
• Minimum number of alpha or numeric characters required (PASSWORD_minimum_alpha and PASSWORD_minimum_digits)
• Special characters

  Alert    

• Never deploy Teamcenter with default passwords. Default passwords are too well known; for example, infodba is the default password for an infodba user.
• Use high-entropy (strong) passwords for all accounts, especially for db2 admin, db2 user, infodba, dcsproxy, operating system user values used for installation, and the DB_CONNECT_STRING value. For example, oiunr0i%%$$9dE is stronger than mypassword.
• The password must not be empty or contain any white space characters, such as space, tab, newline, carriage return, form feed, or vertical tab.
• In addition, the password must not contain any of the following characters:   ! @ $ % = & ' " : ; . < > ( ) { }
• Protect all files containing passwords with OS permissions. Encrypted or not, the "read access" to these files must be guarded because a hacker cannot break the encryption if he can't read the contents.
