regular expression for password with few rules

Question

1. Must be longer than 6 characters

Answer 1

You can use the following regex and get the content of the capturing group to check if your string is valid:

.*\d{3}.*|^([\w\+$#/\\]{6,})$

Working demo

Using \w allows A-Za-z0-9_ if you don't want underscore on your regex you have to replace \w by A-Za-z0-9

For the following examples:

pass12p            --> Pass
pass125p           --> Won't pass
asdfasf12asdf34    --> Pass
asdfasf12345asdf34 --> Won't pass

Match information is:

MATCH 1
1.  `pass12p`
MATCH 2
1.  `asdfasf12asdf34`
