A new question for Activation Email format

Hi: Thanks for skindy, I have got a format for activation email format, which is I need. It shows below:

Dear ##firstname##,

Thank you for your registration on ##domain##.

Please click ##link## to complete your registration and to activate your account.

Your username is ##username##
Your password is ##password##

If you did not request an account, please ignore this e-mail.

Thanks!
- Webmaster

But in the activation email the password show like that:

Your password is e4cf7592d4d4d0eb5244faa1e9838bb472bf9b20:b4f25ee6c 66d413ad782307

The Password should be "11111111". May I know what I can do next?
