I know there is a regular expression field in the web.config section for membership that allows me to specify a regular expression for password strength. The problem is I have no idea how to set it up to simply allow any character to be used in the password. I don't care about length or min right now because I want to migrate users over and then reset the passwords later. Right now I just need to migrate my users over and the membership provider that I am using for my project, restricts # from being used. I got this as a regex:

^.*(?=.{7,})(?=.{1,5}[?,./>'~!@#$%^&*()_+-={}|\:;'<>?,./]).*$

And tried to modify it by setting the 7 to 1. But when I put this in web.config it does not accept it and breaks on build. HELP!

^.*$ 

dprior:

^.*$ 

 Ummm....where do I put this in the RegEx??

Hi

Base on my understanding, you want to reduce the password strength when create membership user, here is an example might help 

        <providers>
          <clear/>
          <add name="AspNetSqlMembershipProvider"
                 type="System.Web.Security.SqlMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"
                 connectionStringName="LocalSqlServer"
                 enablePasswordRetrieval="false"
                 enablePasswordReset="true"
                 requiresQuestionAndAnswer="true"
                 requiresUniqueEmail="false"
                 minRequiredPasswordLength="1"
                 minRequiredNonalphanumericCharacters="0"
                 passwordStrengthRegularExpression="^[^#]*$" />
        </providers>

That *IS* the RegEx.  The entire thing.

^ = matches start of string

. = matches any character

* = matches the preceding expression (in this case '.') zero or more times.

$ = matches the end of the string

Actually, you should probably change it to "^.+$" as the first expression would match an empty string, I believe.  The plus sign is the same as the * sign, except that it matches 1 or more instead of zero or more.

                 passwordStrengthRegularExpression="^[^#]*$" />
        </providers>     

 

 

What if I wanted it so that it would allow ALL characters EXCEPT the # character. What would my RegEx look like?

Hi

The RegEx is   ^[^#]*$
