Remarks<\/span><\/strong><\/span><\/p>\n

\n
Use the PasswordRegularExpression<\/strong> property to define the requirements for passwords used to validate users on your Web site. A common use is to make sure that a user has included symbols other than letters in a password to make it harder for attackers to guess a password. The regular expression is used in addition to any restrictions placed on the password by the membership provider specified in the MembershipProvider<\/a> property. If the membership provider rejects the password for any reason, the text contained in the InvalidPasswordErrorMessage<\/a> property is displayed.If the password entered does not pass the regular expression, the error message contained in the PasswordRegularExpressionErrorMessage<\/a> property is displayed to the user.<\/div>\n<\/div>\n\n\n\n
Example<\/span><\/p>\n
\n
The following code example uses the PasswordRegularExpression<\/strong> property to define a regular expression that checks passwords to ensure that they:<\/p>\n
    \n
  • Are longer than seven characters.<\/li>\n
  • Contain at least one digit.<\/li>\n
  • Contain at least one special (nonalphanumeric) character.<\/li>\n<\/ul>\n

    If the password entered by the user does not meet these criteria, the text contained in the PasswordRegularExpressionErrorMessage<\/strong> property is displayed to the user.<\/div>\n<\/div>\n
