string validation for 3 or more consecutive sequential alphanumeric characters in javascript

Question

I have a requirement for a password validator that the password may not include three alphabetically sequential characters or sequential numbers.

So passwords that include the following are considered invalid values

  abc   

  Abc

  123

Tried to see if I could get it with regex in javascript but I haven't been able to. Has anyone done that and if not regex, any javascript code that would check for sequential characters?

Thank you,
