Hi,

I have to validate the password using regex. The password rule is like at least 1 uppercase and at least 2 numeric.

It works fine except if the character comes at the end of the string.

The regular expression which i am using is

"^(?=.*\d.{2})(?=.*[A-Z].{1})(?=.*[@#$%^&+=].{2}).{8,12}$"

Rules:

  • minimum length = 8
  • minimum uppercase = 1
  • minimum numeric = 2
  • minimum special character = 1

It works for Test123$$, Test$123, TEST123$s, Test123$1, Test12$3 but it fails if the character specified comes at the end of the string like Test123$, Test$a12, Test12aa@, 123aa@@T.

Please let me know if there is any fix for this.
