Looking for a regex - 8 char min w/ 1 num and 1 char

Question

I'm looking for some help creating a regex that requires 8 char (at a minimum) along w/ 1 number and 1 char (not special char). example: a1234567 is valid but 12345678 is not Any help for a regex newb? EDIT: Thanks for the quick replies- the implementation that worked in VB is shown below ``` Dim ValidPassword As Boolean = Regex.IsMatch(Password, "^(?=.*[0-9])(?=.*[a-zA-Z])\w{8,}$") ```

Accepted Answer

something like

```
^(?=.*[0-9])(?=.*[a-zA-Z])\w{8,}$
```

would work

dissected:

- `^` the beginning of the string

- `(?=.*[0-9])` look ahead and make sure that there is at least 1 digit

- `(?=.*[a-zA-Z])` look ahead and make sure there is at least 1 letter

- `\w{8,}` actually match the 8+ characters

- `$` the end of the string

Edit: if you want extra characters (that don't count for the 1 letter requirement) use

```
^(?=.*[0-9])(?=.*[a-zA-Z]).{8,}$
```

this will allow for any character besides newline to be used

If you only want certain characters allowed, replace `\w` in the first regex with `[A-Za-z0-9@#$%^&*]` with your choice of symbols

^(?![0-9]$)(?![a-zA-Z_]$)\w{8,}$
