Regex for password must contain at least eight characters, at least one number and both lower and uppercase letters and special characters

Question

I want a regular expression to check that:

A password contains at least eight characters, including at least one number and includes both lower and uppercase letter

Answer 1

Just a small improvement for @anubhava's answer: Since special character are limited to the ones in the keyboard, use this for any special character:

^(?=.*?[A-Z])(?=(.*[a-z]){1,})(?=(.*[\d]){1,})(?=(.*[\W]){1,})(?!.*\s).{8,}$

This regex will enforce these rules:

• At least one upper case English letter
• At least one lower case English letter
• At least one digit
• At least one special character
• Minimum eight in length

Answer 2

Import the JavaScript file jquery.validate.min.js.

You can use this method:

$.validator.addMethod("pwcheck", function (value) {
    return /[\@\#\$\%\^\&\*\(\)\_\+\!]/.test(value) && /[a-z]/.test(value) && /[0-9]/.test(value) && /[A-Z]/.test(value)
});

1. At least one upper case English letter
2. At least one lower case English letter
3. At least one digit
4. At least one special character

Answer 3

Use the following Regex to satisfy the below conditions:

Conditions:

1. Min 1 uppercase letter.
2. Min 1 lowercase letter.
3. Min 1 special character.
4. Min 1 number.
5. Min 8 characters.
6. Max 30 characters.

Regex:

/^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[#$@!%&*?])[A-Za-z\d#$@!%&*?]{8,30}$/

Answer 4

You can use the below regular expression pattern to check the password whether it matches your expectations or not.

((?=.*\\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[~!@#$%^&*()]).{8,20})

Answer 5

Use this,

((?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[!@#$%?=*&]).{8,20})

It will validate for at least one lowercase, one upper case, one number and the special charecters of (!,@,#,$,%,?,=,*,&).

Minimum length is 8 and maximum length is 20

Answer 6

Minimum eight characters, at least one letter and one number:

"^(?=.*[A-Za-z])(?=.*\d)[A-Za-z\d]{8,}$"

Minimum eight characters, at least one letter, one number and one special character:

"^(?=.*[A-Za-z])(?=.*\d)(?=.*[@$!%*#?&])[A-Za-z\d@$!%*#?&]{8,}$"

Minimum eight characters, at least one uppercase letter, one lowercase letter and one number:

"^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)[a-zA-Z\d]{8,}$"

Minimum eight characters, at least one uppercase letter, one lowercase letter, one number and one special character:

"^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[@$!%*?&])[A-Za-z\d@$!%*?&]{8,}$"

Minimum eight and maximum 10 characters, at least one uppercase letter, one lowercase letter, one number and one special character:

"^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[@$!%*?&])[A-Za-z\d@$!%*?&]{8,10}$"
