I'm having some trouble creating a regex for a password. It has the following requirements :

• at least 10 characters
• at least 1 uppercase letter
• at least 1 lowercase letter
• at least 1 special character

I currently created this line : `

"^(?=(.*[A-Z]) )(?=(.*[a-z]) )(?=(.*[0-9]) )(?=(.*[!@#$%^&*()_ =.]) ){10,}$"

` For a password like : Lollypop56@ it still gives me false.

You forgot a full point after the lookahead of special characters. So it would be:

"^(?=(.*[A-Z]) )(?=(.*[a-z]) )(?=(.*[0-9]) )(?=(.*[!@#$%^&*()_ =.]) ).{10,}$"

CodePudding user response：

The regex should be

"^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[@$!%*#?&])[A-Za-z\d@$!#%*?&]{10,}$"

I tested it on your example

Lollypop56@

and it returns true
