Correct password requirements

Description

The guide to create a password at the sign up says "Password should contain at least one digit, one small letter and one capital letter and should at least contain 8 characters.", however, there is one requirement that is not described here. The password must have an special character.

To Reproduce

Just go to the sign up page and type a valid password according to the description such as "1234567qW", but the password will be invalid, then try adding a special character like "1234567qW@", and the password will be accepted.

Expected behavior

Expected that the password description would be correct, like "Password should contain at least one digit, one special charater, one small letter and one capital letter and should at least contain 8 characters."

Runtime Environment

Docker version 20.10.13 on Ubuntu 20 x86_64

Start at the sign-up page and locate the password requirement description. Update the text to mention the required special character, then verify that a password such as "1234567qW" is rejected and "1234567qW@" is accepted.
