Expression |
^(?=.*[!@#$%^&*()\-_=+`~\[\]{}?|])(?=.*[a-z])(?=.*[A-Z])(?=.*[0-9]).{8,20}$
|
|
Description |
This should require all of the following: An uppercase letter, a lowercase letter, a number and a special character from the provided list. Lastly, it needs to be between 8 and 20 characters long.
A lot of expressions I've found here don't require all four, this should. I'm pretty new at regex though, so I hope that other people will help strengthen this expression.
When testing on this site, make sure you have the Case Insensitive checkbox turned off.
