Required Password Pattern IT policy rule


This rule specifies the permitted structure of a BlackBerry® device password.

Passwords can contain Latin-1 characters only.

Default value

The default value is a null value.


Use the following characters in the password pattern to specify the character type that is permitted and its position in the password:

  • a: Permits any letter.
  • A: Permits an uppercase letter only.
  • c: Permits any consonant letter.
  • C: Permits an uppercase consonant letter only.
  • v: Permits any vowel.
  • V: Permits an uppercase vowel only.
  • N, n, or #: Permits a number only.
  • S, s, or @: Permits a symbol only.
  • ?: Permits any letter, number, or symbol.

If you configure this rule, the user can create a password that is greater than or equal to the length of the pattern on a BlackBerry device. Password characters that exceed the pattern length can be any letters, numbers, or symbols.

Attention: Preventing a particular password character reduces the entropy level and security level of the password.

Minimum requirements

  • Java® based BlackBerry device
  • BlackBerry® Application Suite version 1.0
  • BlackBerry® Device Software version 4.2
  • BlackBerry® Enterprise Server version 4.0 SP6
