Hi All,

I need to do for password strength.

• Passwords must not contain repeating or sequential characters or numbers like 12345 or abcd etc.
• Passwords must not contain a sequence of two (2) or more characters more than once, e.g., a12x12

Thanks

I would not use a regex for this - it is not a good regex task. You could create one, but it would be extremely complex and difficult to understand and maintain.

Use code - it's a lot easier to read when it comes to jobs like this!

My 5!
I'd say, it's not possible with Regex. E.g. how to tell in a generic form to not have sequence of characters, i.e. how to tell that the next must not be the collating successor of the current? Simply the wrong approach.
